Keeping LLMs in Their Lane: Focused AI for Data Science and Research
From R+AI 2025, hosted by R Consortium
Keynote
LLMs are powerful, flexible, easy-to-use… and often wrong. This is a dangerous combination, especially for data analysis and scientific research, where correctness and reproducibility are core requirements. Fortunately, it turns out that by carefully applying LLMs to narrower use cases, we can turn them into surprisingly reliable assistants that accelerate and enhance, rather than undermine, scientific work. This is not just theory—I’ll showcase working examples of seamlessly integrating LLMs into analytic workflows, helping data scientists build interactive, intelligent applications without needing to be web developers. You’ll see firsthand how keeping LLMs focused lets us leverage their “intelligence” in a way that’s practical, rigorous, and reproducible.

What R We Counting?
Speaker(s): Ben Arancibia
Abstract:
GSK Biostatistics mandates that all new tools be written using open-source languages and open-source code achieve parity with proprietary software by the end of 2025. Given this ambitious timeline, someone might ask, “How is the open-source adoption going?” This seemingly simple question involves complexities: What metrics do you track? How to measure success? How to show progress? GSK addressed these by leveraging our internal GitHub data, using open-source R packages like {gh}, scheduling our data pipeline on Posit Connect, and generating diverse reports/dashboards. We’ll share our journey of transitioning to R and other open-source tools, offering insights on scaling full enterprise open-source adoption. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/

Uncharted Nuuk: Data Exploration in Search of the Unexpected (Emil Malta, Statistics Greenland)
Uncharted Nuuk: Data Exploration in Search of the Unexpected
Speaker(s): Emil Malta
Abstract:
Good graphs are more than simple decorations. They are effective tools for challenging your intuition, and can uncover engaging narratives along the way. Using examples from official statistics, this talk shows how tools like API packages can query data from official registers, streamlining ways to import and tidy data, so your time is better spent on story telling with data visualisation. Highlighting Nuuk, a symbol of Greenland’s rapid change, I’ll demonstrate how to use these tools to turn complex registers into clear, impactful stories. If you work with official statistics, as an educator, journalist or in government, this talk offers practical insights for streamlining workflows and crafting engaging visualizations. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/
Trustworthy Data Visualization (Kieran Healy, Duke University) | posit::conf(2025)
Trustworthy Data Visualization
Speaker(s): Kieran Healy
Abstract:
Visualizations are the most widespread, the most immediately accessible, and in some ways the most authoritative-looking way to present results to audiences, including when the audience is just yourself. In this talk I ask: what makes a visualization trustworthy? How do tools like R and ggplot to help us achieve that goal? And what are their limits, especially now that it’s easier than it has ever been to do untrustworthy things with data?

Theming Made Easy: Introducing brand.yml
Speaker(s): Garrick Aden-Buie
Abstract:
brand.yml is an exciting new project from Posit that radically simplifies theming. Every data science tool supports some form of theme and appearance customization, but each app framework, output format, or visualization tool requires its own special syntax for theming.
The goal of brand.yml is to create a portable and unified interface for brand-related theming that can be used anywhere that data science artifacts are produced. As a collaboration between the Shiny and Quarto teams, brand.yml provides a single interface to setting baseline themes in reports and apps across the R and Python ecosystems.
In this talk, I’ll introduce brand.yml and showcase the many ways that brand.yml can bring consistent styles to your data science outputs.

The Psychology of Technologists (Cat Hicks, Catharsis Consulting) | posit::conf(2025)
The Psychology of Technologists
Speaker(s): Cat Hicks
Abstract:
Technology teams are struggling to be heard. Technologists are grappling with high turnover, high burnout, and low resilience in the face of rapidly-accelerating technological change. Even though effective technical teams are an essential part of our world continuing to work, many organizations struggle to understand their technical teams, stuck in old stereotypes that treat technical people like isolated machines. To build a thriving future, we need a new way of working together and understanding our own minds as we build technology. In my empirical research across thousands of developers, technical managers and their teams, we’ve explored what a psychologically-rich environment looks like for modern technologists and found important signals that can guide teams toward greater resilience, innovation, and thriving. In this keynote we’ll unlock access to the psychological sciences and evidence that you can use to make your every day more human.

Same Data, Different Tools: Visualizing with R and Python (Olivia Hebner, Summit)
Same Data, Different Tools: Visualizing with R and Python
Speaker(s): Olivia Hebner
Abstract:
In 2024, our team participated in a data challenge to recreate a visualization from W.E.B. Du Bois’s 1900 Paris Exposition using modern tools. We split into two groups—one using R and the other Python—to compare their strengths and limitations. Both teams used census and geographic data to map county-level populations for 1870 and 1880. Team R used ggplot2 and grid for precise layout control, while Team Python used matplotlib’s subplot system for structuring. This challenge pushed us beyond more traditional data science visualizations, requiring creative approaches to mimic Du Bois’s design. Attendees will gain insights into data wrangling, visualization techniques, and layout design to guide their own projects.

Running a polyglot data science community
Speaker(s): Melissa Van Bussel
Abstract:
Running a successful data science community is CHALLENGING! And it’s even more challenging when you have a very large group of people, especially if they use different programming languages or are at different steps in their data journeys. It can be done, though, and in my talk I’ll share the strategies that we’ve been using at Statistics Canada to keep the 1000+ members of our R and Python User Group interested and involved. I’ll also talk about why you don’t have to limit the target audience of your data science community to just one group – creating polyglot communities that embrace multiple programming languages is a great way to ensure the long-term success and relevance of these groups. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/

R & Python playing nice, in production
Speaker(s): Claudia Penaloza
Abstract:
Hi, I’m Claudia Peñaloza, a Data Scientist at Continental Tires, where going data-driven can be an adventure. What started as a proof of concept a few years ago, evolved into Conti’s first-ever Predictive Machine Learning Model for R&D! A baby, a wedding, two lateral moves, and three hires later, our team had also evolved… from mostly R to mostly Python developers. Rewriting 1000+ commits? No thanks. Instead, we got R and Python to play nice. With Renv, Poetry, and Docker, we keep things reproducible, portable, and deployable on various ML-Ops platforms. The takeaway? With the right tools, teams can mix and match languages, leveraging the best in each, and still build solid, scalable solutions. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/
Quarto for Business Collaboration & Technical Documentation in Word docx format (Bill Pikounis, J&J)
Quarto for Business Collaboration and Technical Documentation in Word docx format
Speaker(s): Bill Pikounis
Abstract:
Microsoft Word documents have remained a critical channel of statistical evidence and influence for the manufacturing of a safe and effective supply of therapies to treat diseases. The incorporation of statistical content – narratives, graphs, and tables – into health authority dossiers worldwide requires speed in terms of days and sometimes hours to generate statistical source content for decision-making and official documentation.
Quarto provides an efficient solution to address these needs. This presentation illustrates and covers concepts of the solution that builds upon R and the Posit platform to reliably produce an automated and flexible workflow for figure and table captions, autonumbering, and cross-referencing in docx format. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/
Putting an {ellmer} AI in production with the blessing of IT (Andrie de Vries) | posit::conf(2025)
Putting an {ellmer} AI in production with the blessing of IT
Speaker(s): Andrie de Vries
Abstract: I had an idea to automate a process by letting an AI extract information from PDF attachments. Writing the 20 lines of {ellmer} code was very simple. My users loved the idea. But IT had different feelings, especially initially. It took multiple design changes to get IT comfortable with running experiments in our financial system. They need a solution that is secure, with guardrails, wouldn’t leak sensitive information and could be easily maintained. We wrote a simple browser extension to reduce the friction of copy/paste between different systems. If you want to put an AI in production, make sure you consider the impact on other teams, in particular IT and Information security.

Purrrfectly parallel, purrrfectly distributed
Speaker(s): Charlie Gao
Abstract:
purrr is a powerful functional programming toolkit that has long been a cornerstone of the tidyverse. In 2025, it receives a modernization that means you can use it to harness the power of all computing cores on your machine, dramatically speeding up map operations.
More excitingly, it opens up the doors to distributed computing. Through the mirai framework used by purrr, this is made embarrassingly simple. For those in small businesses, or even large ones – every case where there is a spare server in your network, you can now put to good use in simple, straightforward steps.
Let us show you how distributed computing is no longer the preserve of those with access to high performance compute clusters.

Precision Medicine for All: Using Tidymodels to Validate Breast Cancer PRS in Brazil
Speaker(s): Flávia E. Rius
Abstract:
Polygenic risk scores (PRS) are a powerful way to measure someone’s risk for common diseases, such as diabetes, cardiovascular disease, and cancer. However, most PRS are developed using data from European populations, making it challenging to generalize results to other ancestries. In this talk, I’ll show how I used tidymodels tools—like yardstick, recipes, and workflows—to calculate metrics and validate a breast cancer PRS in the highly admixed Brazilian population. You will learn how to leverage tidymodels to make precision medicine more inclusive. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/

Polyglot Data Science: Why and How to Combine R and Python (Jeroen Janssens) | posit::conf(2025)
Polyglot Data Science: Why and How to Combine R and Python
Speaker(s): Jeroen Janssens
Abstract:
Doing everything in one language is convenient but not always possible. For example, your Python app might need an algorithm only available as an R package. Or your R analysis might need to fit into a Python pipeline. What do you do? You take a polyglot approach! Many data scientists hesitate to explore beyond their main language, but combining R and Python can be powerful. In my talk, I’ll explain why polyglot data science is beneficial and address common concerns. Then, I’ll show you how to make it happen using tools like Quarto, Positron, Reticulate, and the Unix command line. By the end, you’ll gain a fresh perspective and practical ideas to start. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/

Making the most of artificial and human intelligence for data science (Hadley Wickham, Joe Cheng)
Making the most of artificial and human intelligence for data science
Speaker(s): Hadley Wickham; Joe Cheng
Abstract:
This presentation explores the complex and often contradictory nature of large language models (LLMs) in data science, acknowledging the simultaneous excitement and apprehension that we feel toward these technologies. We’ll provide a practical framework to help you understand the LLM ecosystem (from foundation models and hosting to SDKs and applications) that supports our current philosophy: augmenting, not replacing human intelligence. The talk demonstrates how Posit is addressing this space through two complementary approaches: building SDKs and tools that help you create your own LLM-powered solutions, and developing integrated LLM capabilities directly into data science workflows through tools like Positron assistant and databot. We’ll showcase practical, immediately useful applications while addressing current limitations, providing you with both the emotional preparation and technical foundation needed to effectively leverage LLMs in their data science practice today. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/

History repeats itself: What the Du Bois Challenge taught me about reproducing design (Simi Ndaba)
History repeats itself: What the Du Bois Challenge taught me about reproducing visualisations
Speaker(s): Simisani Ndaba
Abstract:
In 2024, I participated in the Du Bois challenge to recreate W.E.B Du Bois’s iconic 1900s charts on African American sociology. By reproducing the old graphs and their annotations, themes, accessibility and visible contrasts, I levelled up my visualisation skills. I learnt about complexity of design, colour palettes, fonts, styling, and of course appropriate R packages. This experience empowered me beyond the DuBois challenge and used what I learnt to take part in the 30-day chart challenge, Genuary and Tidy Tuesday. In this talk, I will share what I learnt so that you too can more easily become familiar with unfamiliar charts and craft your own visualizations to regale stories. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/
Hacking Productivity with LLMs (Nic Crane, NC Data Labs) | posit::conf(2025)
Hacking Productivity with LLMs: What Works (and What Doesn’t)
Speaker(s): Nic Crane
Abstract:
Over the past 18 months, I’ve used large language models (LLMs) in a series of experiments to improve my productivity as a developer on open source projects in R. I wanted to see if these tools could help with the repetitive, frustrating, or time-consuming parts of development, freeing me up to focus on the interesting problems. The results were mixed: some of these experiments were wildly successful, but others were clear failures.
In this talk, I’ll share what worked, what didn’t, and what I learned. I’ll explore important questions to ask around the kinds of tasks LLMs are good for and where they fall short, how to use LLMs to build lasting skills, and why in some cases, investing in human connection pays off more than AI assistance. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/

From Data to Dollars: Improving Medical Billing Accuracy Using NLP (Julianne Gent, Emory Healthcare)
Protecting our Healthcare Heroes: Using Natural Language Processing to Prevent Billing Mistakes in Healthcare
Speaker(s): Julianne Gent
Abstract:
Maintaining accurate billing documentation in healthcare is essential to prevent revenue loss and preserve patient satisfaction. I’m Julianne Gent, Analytics Developer for Emory Digital, and I’m here to discuss the natural language processing algorithm we built utilizing an automated SQL-to-R pipeline. This algorithm uses packages ‘odbc’ and ‘stringr’ to import SQL queries into R, recognize billing patterns, and extract billing time. Our algorithm accurately captured billing data for 93% of over 250,000 notes. The billing provided by our hospital’s medical software? Only 40%. Our algorithm showed that an SQL-to-R pipeline can improve billing documentation and accuracy, and we are confident that it can be applied to many other industries. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/

Speaker(s): Laura Gast
Abstract:
In a field driven by precision, the power of failure is often overlooked. This talk digs into the paradoxical benefit of error in data science, drawing on high-profile missteps in data handling and personal anecdotes of falling short. Using examples from errors big and small leading to impacts big and small to the everyday misinterpretation or misuse of data that happens everywhere, we’ll focus on how to get the best out of failure. While some level of error is inevitable in data science, the most resilient and forward-thinking teams realize that errors can drive innovative and creative solutions that may not have been discovered if everything had gone as planned. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/

Election Night Reporting Using R & Quarto (Andrew Heiss & Gabe Osterhout) | posit::conf(2025)
Election Night Reporting Using R & Quarto
Speaker(s): Gabe Osterhout; Andrew Heiss
Abstract:
Election night reporting (ENR) is often clunky, outdated, and overpriced. The Idaho Secretary of State’s office leveraged R and Quarto to create a better ENR product for the end user while driving down costs using the open-source software we all know and love. With help from Dr. Andrew Heiss, R was used in every step of the process—from {dbplyr} backend to visualizing the results using {reactable} tables and {leaflet} maps, combining the output into a visually appealing Quarto website. Quarto was the ideal solution due to its scalability, quick deployment, responsive design, and easy navigation. In addition, Dr. Heiss will discuss the advantages of using a {targets} pipeline and creating programmatic code chunks in Quarto.

Speaker(s): James Wade
Abstract:
Many data scientists find themselves building Shiny apps for one-off presentations, client meetings, or teaching demonstrations. These “disposable” apps can suffer from overengineering, leading to unnecessary development time and complexity. Or, the apps never get built because the development hill is too high to climb. This talk covers disposable Shiny apps - intentionally minimal applications designed for specific, short-term needs. We’ll explore strategies for rapid development, including reusable templates, coding assistants, efficient styling, and design principles that prioritize speed and clarity. This talk will show how this approach can transform a typical week-long development process into a few hours while maintaining polish.

Can I trust that package? (Colin S Gillespie, Jumping Rivers) | posit::conf(2025)
Can I trust that package?
Speaker(s): Colin S Gillespie
Abstract:
We often forget, surrounded by hex stickers and bad R package puns, that not everyone is as trustworthy as us. This, I suppose, means that when IT asks, “Is this package valid, secure, and trustworthy?” it’s not that unreasonable a question. But this throws up multiple issues. There are thousands of R packages on CRAN, and that doesn’t include the R-universe, Bioconductor, and GitHub. Packages are updated all the time, so how do we keep up? More to the point what does valid, secure and trustworthy even mean?
In this talk, I’ll discuss the litmusverse. A suite of packages for assessing a package risk. Importantly, it’s not one size fits all. Instead, it’s about defining your risk appetite and acting accordingly. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/

Abstract:
Over one billion people worldwide use spreadsheets to manage and analyse data, often styling cells and their contents to highlight or distinguish values. This formatting is often used to encode additional data (for example, indicating groups with colors) but most data science tools are unaware of data expressed as formatting. This talk summarizes my progress addressing the gap between formatted spreadsheets and the modern data stack. First, by championing data organization best practices, then by bringing spreadsheet contents and their formatting together into R for further analyses (unheadr package), and finally how translating format to data helped me develop tools (forgts package) for converting formatted spreadsheets to gt objects.

Speaker(s): Katerina Gapanenko
Abstract:
The Canadian Institute for Health Information is diving into open source, transitioning our 300+ analysts and all our analytics code from proprietary software to R and Python. We started 3 years ago, and over that time we have migrated 700,000+ lines of code, navigating waves of change while adapting to new IT environments and workflows. Challenges like technical barriers, workload balancing, and resistance to change were tackled through training, mentorship, and executive support. More than tools, this shift transforms our culture—turning siloed developers into fearless swimmers. Success requires training, teamwork, and courage. Organizations making a similar leap should start small, invest in training, and stay adaptable to stay afloat. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/

Web applications with Shiny and React and AI (Winston Chang, Posit) | posit::conf(2025)
Web applications with Shiny and React (and AI)
Speaker(s): Winston Chang
If you’ve ever wanted to have complete control over the UI for a Shiny application, this talk might be for you. In this talk I’ll show how to integrate a back end written in Shiny (for R or Python) with a front end written in React.js. This lets you combine Shiny’s reactivity with the flexibility of the React web development ecosystem.
In the past, writing a front end in React was a large time investment, and would be reserved only for a serious project. However, with today’s agentic AI coding tools, it can make sense to create a React front end even for smaller-scale applications. But even with AI involved, you will still need to know some React or be willing to learn about it.

Use Your Data Skills for Good (Sharon Machlis) | posit::conf(2025)
Use Your Data Skills for Good: Ideas for Community Service Speaker(s): Sharon Machlis
Abstract: Community service doesn’t have to mean finding a group where your skills match their needs. You can also see a data-related need and jump in to fill it.
Are there interesting things to do in your town, but no one place to find them? You could create a searchable, auto-updating local events calendar.
Do you live someplace where local election results aren’t published the way you’d like people to see them? If data is publicly available, you could analyze and publish it yourself.
You’ll leave this session with some ideas on how your data skills can help your community – even if you’re not ready to commit to formal volunteering with an outside organization.

Trust, but Verify: Lessons from Deploying LLMs in a Large Health System (Timothy Keyes)
Trust, but Verify: Lessons from Deploying LLMs in a Large Health System
Speaker(s): Timothy Keyes
Abstract:
Large language models (LLMs) are transforming how data practitioners work with unstructured text data. However, in high-stakes domains like medicine, we need to ensure that “hallucinated” clinical details don’t mislead clinicians.
This talk will present a framework for evaluating and monitoring LLM systems, drawing from a real-world deployment at Stanford Health Care. We will describe how we built and assessed an LLM-powered system for real-time, automated chart abstraction within patients’ electronic health records, focusing on methods for measuring accuracy, consistency, and safety. Additionally, we will discuss how open-source tools like Chatlas and Quarto powered the work across our team’s combined Python- and R-based workflows. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/

The Curse of Documentation (Michael Chow, Posit) | posit::conf(2025)
The Curse of Documentation
Speaker(s): Michael Chow
Abstract:
In Greek mythology, Tantalus was doomed to stand with a lake of water below him and branches of fruit close above. When he went to drink the water it receded, and when he reached to eat the fruit it was blown beyond his grasp. What he needed was forever at arms length.
Software documentation often puts users in a similar bind. The information is there, but something doesn’t quite connect. Maybe you try and fail to adapt an example to your use case. Maybe it’s unclear how a bunch of functions fit together.
In this talk, I’ll discuss how effective user guides–like R for Data Science and the React.js guide–break the curse. I’ll focus on three factors behind effective guides: strategic information, inductive learning, and task sequencing. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/
Teaching data visualization with R entirely in Quarto (Claus Wilke, UT Austin) | posit::conf(2025)
Teaching data visualization with R entirely in Quarto
Speaker(s): Claus Wilke
Abstract:
When teaching a programming course, we may want to employ several different modes of content delivery. First, slides. (And it should be easy to integrate code and code output into them.) Second, practical exercises, where students can try out programming concepts in a guided manner. Third, an in-class live programming environment, to ad-lib during lectures. Fourth, a framework for graded assignments. Fifth, a class website. All of these components can be created with Quarto and webR. I will explain how I used these technologies for my data visualization class at UT Austin, covering how the different components work, what issues I encountered, and what I think best practices are if you want to create a similar course yourself.

Teaching Data Sharing through R Data Packages
Speaker(s): Kelly McConville
Abstract:
Data science courses tend to teach students reproducible workflows. However, the origin of the data used in these workflows and definitions of the variables used are often not emphasized. This talk addresses this gap by focusing on how to teach students effective data sharing through the creation of R data packages. We’ll explore how to leverage key packages, such as devtools and usethis, and will demonstrate how to guide students in generating appropriate documentation through ReadMes, help files, and vignettes. Furthermore, we’ll discuss common pitfalls encountered when first learning to create R packages and will propose how to structure a project assignment where an R data package serves as the primary deliverable.

surveydown: A Markdown-Based Platform for Interactive and Reproducible Surveys Using Quarto and Shiny
Speaker(s): John Paul Helveston
Abstract:
This talk introduces the surveydown R package and survey platform, which leverages the Quarto publication system and R shiny web framework to create reproducible and interactive surveys. While most survey platforms rely on graphical interfaces or spreadsheets to define survey content, surveydown uses plain text (markdown and R code chunks), enabling version control and collaboration via tools like GitHub. It supports complex features like conditional skip logic, dynamic questions, and complex randomization as well as a diverse set of question types and formatting options. The open-source package gives researchers full control over survey implementation and data storage, with reproducible workflows that integrate with R data analysis.

shinystate: Launching collaboration and session management to new heights in Shiny applications
Speaker(s): Eric Nantz
Abstract:
Shiny is being used more regularly as a front end to sophisticated workflows in data science, often with a large number of inputs and intricate reactivity. End users desire a way to save their progress through the application workflow and share their state of the application with others for review. For small applications, the existing Shiny bookmarkable state feature is a valid approach. However, many of the production Shiny applications I’ve created require more granular control. Enter {shinystate}, my new R package that offers an intuitive class system and integration with {pins} to let developers choose where to save application state, ability to save multiple sessions at once, and bring collaboration to new heights for end users.

Semantic Search for the Rest of Us with DuckDB (Marcos Huerta, Carmax) | posit::conf(2025)
Semantic Search for the Rest of Us with DuckDB
Speaker(s): Marcos Huerta
Abstract:
Semantic search matches a search query against documents not just by directly matching words, but by ranking results using semantic meaning - for example searching for “cat” could also turn up documents that have “tiger.”
While many enterprise level solutions exist for semantic search, I will show a low memory technique in Python that enables live semantic search for small to medium document collections that need to be deployed in constrained memory/ CPU environments - such as Posit Connect Cloud or a small cloud server.
I will show how a web app (such as Shiny for Python) using just a few hundred megabytes of memory can enable live search using the fixed array support in DuckDB, and the open source library LlamaCPP. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/

Observability at scale: Monitoring Shiny Applications with OpenTelemetry
Speaker(s): Barret Schloerke
Abstract:
Understanding what happens behind the scenes in production Shiny applications has always been challenging. When users experience slow response times or unexpected behavior, developers are left guessing where bottlenecks occur. This talk introduces OpenTelemetry integration for Shiny for R, a new approach to profiling code and understanding application behavior.
Through a chat-enabled weather application, we’ll explore how complex user interactions trigger cascading events across multiple processes. You’ll learn how OpenTelemetry’s “high-quality, ubiquitous, and portable telemetry” can provide complete visibility into your Shiny application’s performance with minimal setup… just a few environment variables!
After walking through the chat app, you’ll have a taste of how to implement comprehensive monitoring for your Shiny applications in production, enabling you to proactively identify and resolve unexpected performance issues.

Modular, layout-as-code approach for customizable Shiny dashboards (Kim Schouten, De NZa)
Modular, layout-as-code approach for customizable Shiny dashboards
Speaker(s): Kim Schouten
Abstract:
To improve government supervision in the healthcare space, we have designed a Shiny dashboard that enables us to adhere to GDPR and other regulations and share different bits of information with different types of stakeholders. For that, we have implemented a ‘layout-as-code’ system where each user can have its own layout of pages and modules, stored as json in the database. Users have the option to drag and drop modules to different locations or change the layout altogether, adding and removing modules as needed! For developers, this system of loosely coupled modules helps to quickly contribute to the project as a new module needs only a couple of lines of code to integrate it within the framework.

Making Things Nice in Python (Rich Iannone, Posit) | posit::conf(2025)
Making Things Nice in Python
Speaker(s): Rich Iannone
Abstract:
When working on the Great Tables and Pointblank Python packages, we’ve tried to make them ’nice’. These packages give you a lot of convenient options, and a large volume of docs and examples. In the Python world, this might be received differently than it would be in R. Whether it was integrating Polars selectors in Great Tables or accepting a multitude of DataFrames and DB tables in Pointblank, these design choices can be seen as surprising things to established Python developers.
However, I argue it’s good to be doing this! People are benefitting from these approaches. I’ll share a few of these developer stories with the takeaway being that Python packages could and should pay attention to good user experience. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/

Lift Off! Building REST APIs that Fly
Speaker(s): Joe Kirincic
Abstract:
Picture the scene: you’ve successfully deployed your ML model as a plumber API into production. Your company loves it! One team uses the API’s predictions as an input to their own ML model. Another team displays the predictions in an internal Shiny app. But once adoption reaches a certain point, your API’s performance starts to degrade. What can you do to help your service maintain high performance in the face of high demand? In this talk, we’ll show some strategies for taking your API performance to the next level. Using two R packages, {yyjsonr} and {mirai}, we can augment our API with faster JSON processing and better responsiveness through asynchronous computing, allowing our services to do great things at scale at no additional cost. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/

Speaker(s): Mine Cetinkaya-Rundel
Abstract:
A considerable recent challenge for learners and teachers of data science courses is the proliferation of the use of LLM-based tools in generating answers. In this talk, I will introduce an R package that leverages LLMs to produce immediate feedback on student work to motivate them to give it a try themselves first. I will discuss technical details of augmenting models with course materials, backend and user interface decisions, challenges around evaluations that are not done correctly by the LLM, and student feedback from the first set of users. Finally, I will touch on incorporating this tool into low-stakes assessment and ethical considerations for the formal assessment structure of the course relying on LLMs.

Instant Impact: Developing {docorator} to Simplify R Adoption for Teams
Speaker(s): Becca Krouse
Abstract:
Although R supports comprehensive analysis workflows, creating polished, production-ready PDFs directly from R remained a challenge for our pharma teams. With teams facing looming deadlines, our R enablement team swiftly created {docorator}—an open-source R package that transforms R-based tables and figures into production-level PDFs. By adorning results with “decorations” like headers, footers, and page numbers, {docorator} produces seamless, polished documents. Powered by Quarto, it also auto-sizes {gt} tables for user ease. Attendees will learn how {docorator} became the missing piece in GSK’s R workflows and learn how focusing on quick, simple solutions can have a lasting impact. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/

Get Your Ducks in a Row with Databases (Melissa Albino Hegeman, NYS OGS) | posit::conf(2025)
Get your ducks in a row… faster Shiny apps with DuckDB
Speaker(s): Melissa Albino Hegeman
Abstract:
Our small team tackled sluggish Shiny applications by implementing DuckDB as a cache layer, transforming slow, resource-intensive operations into responsive user experiences. Initially, our application pulled data directly from SQL Server, performing real-time aggregations that resulted in poor response times. By restructuring our pipeline to pre-compute results in DuckDB, we significantly improved performance. This presentation demonstrates how we identified bottlenecks, implemented DuckDB integration, and measured improvements. We’ll share practical examples of DuckDB integration with R, discuss trade-offs, and show how this accessible solution can benefit other small teams with limited resources. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/

Abstract:
Opening a Shiny app to endless dropdowns and scattered filters leads to immediate disengagement and feeling like “death by dropdown”. This talk introduces the Behavioral Insights Design (BID) Framework, a behavioral science roadmap that transforms overwhelming dashboards into guided user journeys. Using the “Interfaces Need A Smart Vision” mnemonic, we’ll explore five stages: Interpret user needs through data storytelling, Notice cognitive friction points, Anticipate user behavior, Structure the application, and Validate & empower users. Drawing from established theories and real-world production examples, attendees will see how applying behavioral science can dramatically reduce the time between “Where do I even start?” and “Aha, now I get it!”. You’ll leave with practical techniques using the new {bidux} package to help transform user confusion into confident exploration and build dashboards that guide users toward better decisions (and fewer ghosted users).

Careful exercise design with WebR/Pyodide can make the difference between empowering learners and demotivating them. With our R-Bootcamp and other exercises as examples, I show scaffolding methods for teaching data science concepts gradually, as well as other design considerations. I’ll finish up with showing you how to set up WebR up in your slides and websites for your Data Science Learners.

Design of Everyday Shiny Apps (Casey Aguilar-Gervase & Maya Gans, Atorus) | posit::conf(2025)
Design of Everyday Shiny Apps
Speaker(s): Casey Aguilar-Gervase; Maya Gans
Abstract:
Donald Norman’s Design of Everyday Things shows how even smart people struggle with bad design—flipping the wrong switch, pushing a door instead of pulling. The same issues exist in Shiny apps, where function often outweighs experience. But as a Shiny developer, you are the door designer, and it’s your responsibility to create user-friendly tools. Not to worry—good design isn’t just for designers. You don’t need an art degree to build intuitive, visually appealing apps. This talk covers composition, color theory, scale, and proportion—practical rules to improve usability. We’ll show real-world examples and code-based strategies to bring these principles to life. Because good design isn’t a luxury—it’s a necessity.

Building Governable ML Models with R (Tom Shafer, Elder Research) | posit::conf(2025)
Building Governable ML Models with R
Speaker(s): Tom Shafer
Abstract:
For a model to provide value in production, it must be fit for purpose, deployable, and maintainable over time. We know that R provides a host of tools and packages for building good models, but the language and ecosystem also provide tools to help us build these kinds of maintainable production systems. This talk will present techniques, adapted from software engineering, that provide a stable foundation for building models and writing all the accompanying code that’s often needed to train, test, and update models over time. Those attending this talk will learn how, by centering model development on packages, writing tests, creating intuitive S3 methods, and more, we can build modularized, testable code that makes our models easier to monitor and update over time.

Birthing the pregnancy package (Ella Kaye, University of Warwick) | posit::conf(2025)
Birthing the pregnancy package
Speaker(s): Ella Kaye
Abstract: When I was pregnant, I wrote a personal, private package for date and medication calculations, hard-coded with my data. I thought it would be easy to adapt for general use, but no! I wanted the user experience to be excellent, but how to avoid them repeatedly entering the same due date and meds? How to print useful, nicely formatted, grammatically correct information to the console? How to test a package that relies on the current date? Using the pregnancy package as a case study, I’ll show how to take advantage of base R features such as global options and %||%, how the cli and rlang packages came to the rescue for messages and how testthat’s new mocking features saved the day (literally!) to create a package that’s a pleasure to use.

AskRADS: An AI Recommendation Agent for Maximizing ROI of Data Science Collaborations (Regis James)
AskRADS: An AI Recommendation Agent for Maximizing the ROI of Data Science Collaborations
Speaker(s): Regis A. James
Abstract:
Blockers to crucial data-driven decisions can often be a challenge. To address this, we established RADS, the Regeneron Analysts and Data Scientists, as a Community of Practice for exchanging strategies on eliminating these obstacles. RADS has grown to nearly 500 members, creating a new challenge: avoiding redundancy and helping non-RADS colleagues find the right experts. To solve this, we developed AskRADS, an AI agent on Posit Connect that provides recommendations based on discussions, experts, and relevant resources. It uses R, Shiny for Python, FastAPI, LangGraph, Neo4j GraphRAG, and MySQL. This talk will cover its architecture, AI search solutions, and optimization techniques. posit::conf(2025) Subscribe to posit::conf updates: https://posit.co/about/subscription-management/
Approaching Positron from RStudio (Mauro Lepore, Recast) | posit::conf(2025)
Approaching Positron from RStudio Speaker(s): Mauro Lepore
Abstract: Many data science teams that traditionally worked with R and RStudio are now attracting developers with experience in Python and VS Code. Positron is a polyglot IDE supporting both R and Python and incorporating tools from both RStudio and VS Code. However, jumping straight from one familiar IDE to an unfamiliar one can be intimidating, slow down productivity, and impair adoption.
In this talk, I’ll show some tools and techniques you can use in RStudio and VS Code to start your transition to Positron today—with minimal friction—while staying productive in your preferred IDE.

AI Coding Assistants: Hype, Help, or Hindrance?
Speaker(s): Rebecca Barter
Abstract:
AI coding assistants like ChatGPT, GitHub Copilot, and Codeium promise to revolutionize our coding workflows—but how useful are they in practice? Are they our new overlords here to take our jobs? Or just a passing gimmick? I think the reality lies somewhere in between, and that understanding these tools is key to staying relevant in today’s rapidly evolving data science ecosystem.
In this talk, I’ll show how I’ve used these AI tools in RStudio, Positron, and VS Code to speed up both my advanced R workflows as well as my learning experience as an intermediate Python programmer, providing examples, pitfalls, and best practices.

Deploying Scikit-learn models for in-database scoring with Snowflake and Posit Team
Modern data science workflows often face a critical challenge: how to efficiently deploy machine learning models where the data lives. Traditional approaches require moving large datasets out of the database for scoring, creating bottlenecks, security concerns, and unnecessary data movement costs.
In this demo, Nick Pelikan at Posit highlights how orbital bridges the gap between Python’s rich ML ecosystem and database-native execution by converting scikit-learn pipelines to optimized SQL. This enables data scientists to:
- Use familiar Python tools for model development
- Automatically translate complex feature engineering to SQL
- Deploy models without rewriting code in different languages
- Maintain model accuracy through faithful SQL translations
While this example focuses on Python, Nick also gave this demo using Orbital for R users: https://youtu.be/pnEjYNgOG9c?feature=shared

Creating tests for Shiny for Python apps | Karan Gathani | Posit
With the Shiny for Python v1.0 release, Shiny provides a simple way to create a test file for your Shiny app. The shiny add test command is a helpful CLI tool for Shiny app developers. It simplifies the process of creating test files for their applications.
When you run this command, it prompts you to input two pieces of information: the path to your Shiny app file and the desired location for the new test file.
Once you provide these details, the command automatically generates a test file at the specified location. This new file includes a pre-made test template, giving you a solid starting point for writing your app’s tests.

UDFs enable you to execute R functions within Spark, harnessing Spark’s processing power and combining the strengths of both tools.
In this tutorial, you’ll learn how to:
- Open Posit Workbench as a Databricks user
- Start a Databricks cluster within Posit Workbench
- Connect to a cluster within Posit Workbench
- View Databricks data in RStudio
- Create a prediction function
- Create a user-defined function with sparklyr

Reproducible data science with webR and Shinylive | George Stagg | Posit
A fundamental principle of the scientific method is peer review and independent verification of results. Good science depends on transparency and reproducibility. However, in a recent study a substantial 74% of research code failed to run without errors, often caused by diverse computing environments. This talk will discuss the principles of numerical reproducibility in research and show how software can be pinned to specific versions and self-contained as a universal binary package using WebAssembly. This ensures seamless reproducibility on any machine equipped with a modern web browser and, using tools such as Shinylive, could provide a new way for researchers to share results with the community.

Great Tables: Make beautiful, publication quality tables in Python | Rich Iannone & Michael Chow
Tables are undeniably useful for data work. We have many great DataFrame libraries available in Python, and they give us flexibility in terms of manipulating data at will, but what happens when presenting tables to others?
It’s nice to display tables. Tables can efficiently carry information, just like plots do, and at times it is the better way of presenting data. Indeed, it is time to bridge the divide between raw DataFrame output and wondrously structured tables suitable for publication.
Now, let us turn our attention to the state of ‘display tables’ in 2024. Let us go over what comprises key components for building effective information displays in tables. It may surprise one how new a well-crafted table can be hewn. We’ll take a look at the combinations of Python packages that fit together to make this important task possible, and marvel together at the tabular results they can provide!

{shinylive}: Serverless Shiny Apps | Barret Schloerke | Posit
In the rapidly evolving landscape of web technologies, the integration of R (and Python) with modern web frameworks has become increasingly important for data scientists and developers. This presentation introduces {shinylive}, a new R package that exports Shiny applications to be run within statically hosted websites. We will explore the capabilities of {shinylive} through its use of the innovative R package {webR}, which allows for the execution of R code in the browser (via WebAssembly and service workers) without the need for a centralized server.
The presentation will cover the technical foundation of {shinylive}, including its architecture and the integration process with Quarto documents. We will also discuss the practical aspects and drawbacks of exporting Shiny apps with {shinylive}, highlighting the ease of exporting apps to a folder for local use or hosting them on GitHub pages.
{shinylive} bridges the gap between Shiny and static websites, making it a valuable resource for interactive data analysis and presentation.

Analyze and explore data stored in Snowflake using R
James Blair, Senior Product Manager, Cloud Integrations at Posit, will demonstrate using the R language to analyze and explore data stored in Snowflake. He will also show you how easy it is to set up an R environment inside Posit Workbench that runs as a native app on Snowpark Container Services.
You also find out how using the dbplyr interface can be used to push computation data into Snowflake, giving you access to greater memory and compute power than in a standard R session.
It’s easy to get started. In just a few minutes, you can work in your R session securely inside Snowflake using the RStudio Pro IDE in Posit Workbench. Posit also supports VS Code and Jupyter for data scientists who prefer to work in other languages like Python, so you can continue to use the tools you know and love.

Joe Cheng | Managing long-running operations in Shiny | Posit
It’s been years since Shiny evolved to allow asynchronous operations within applications, improving scalability. The introduction of the {promises} package enabled concurrent processing between multiple Shiny sessions, a significant step forward in handling background tasks. However, this did not address the need for intra-session concurrency, where users expect to interact with the application while long-running calculations are executed in the background.
Recently, we added a new ExtendedTask feature to Shiny to allow for such intra-session concurrency. This new feature provides a different approach for developers to incorporate asynchronous tasks, enabling smoother user interactions during intensive computations. Alongside ExtendedTask, this talk will also discuss newer methods for launching asynchronous tasks, besides the usual {future} package. The focus will be on the practical application and integration of these features into Shiny applications.

You Can Lead a Horse to Water…Changing the Data Science Culture for Veterinary Scientists
Presented by Jill MacKay
A retrospective look at supporting data science skills in a research-focussed veterinary school
This is a talk about environment management, but not in the way you’re thinking. In many industries, domain-specific experts need enough understanding of data science to support their work and communicate with data scientists, but often have insufficient training in these skills, and limited time with which to obtain data science skills and practice them. This is particularly challenging for those who are interdisciplinary and have limited control over their workload, such as medics and field scientists. In this talk, an educational scientist describes the previous 10 years of supporting veterinary scientists to adopt open science practices surrounding data science. What worked, what failed miserably, and reflections on why it can be so hard to get a horse to drink.

Why You Should Add Logging To Your Code (and make it more helpful) - posit::conf(2023)
Presented by Daren Eiri
Learn how the log4r package can help you better understand the errors your code may produce, and how to also get promptly alerted for severe errors by leveraging cloud monitoring solutions like Azure Monitor or AWS CloudWatch
When an error happens in your API, Shiny App, or quarto document, it is not always clear what line of code you need to look at, and the error messages aren’t always helpful. By walking through a simple API example, I show how you can use logging packages like log4r to provide error messages that make sense to you. I also show how you can use cloud-based data collection platforms like Azure Monitor or AWS CloudWatch to set up alerts, so you can get notified by email or text message for those severe errors that you need to be immediately aware of.
Gain more visibility into the health of your code by incorporating logging and pushing your logs to the cloud.

What an Early 2000s Reality Show Taught Me about File Management - posit::conf(2023)
Presented by Reiko Okamoto
Clutter, whether it’s physical or digital, destroys our ability to focus; home organization ideas can be extended to create an workspace where analysts feel inspired to work with data.
Ideas from home organization shows are surprisingly applicable to file management. Using a room divider to establish dedicated zones for different activities in a studio apartment is analogous to creating self-contained projects in RStudio. Likewise, swapping mismatched hangers with matching ones to tidy a closet resembles the adoption of a file naming convention to make a directory easier to navigate.
In this talk, I will share good practices in file management through the lens of home organization. We all know that clutter, whether it is in our physical space or on our machine, destroys our ability to focus. These practices will help R users of all levels create a serene, relaxing environment where they feel inspired to work with data.

We Converted our Documentation to Quarto - posit::conf(2023)
Presented by Melissa Van Bussel
Elevate your Quarto projects to new heights with these practical tips and tricks!
“Wiki”, “User Guide”, “Handbook” – whatever you call yours, we converted ours to Quarto!
A year ago, my team’s documentation, which had been created using Microsoft Word, was large and lacked version control. Scrolling through the document was slow, and, due to confidentiality reasons, only one person could edit it at a time, which was a significant challenge for our team of multiple developers. After realizing we needed a more flexible solution, we successfully converted our documentation to Quarto.
In this talk, I’ll discuss our journey converting to Quarto, the challenges we faced along the way, and tips and tricks for anyone else who might be looking to adopt Quarto too.

Visualizing Data Analysis Pipelines with Pandas Tutor and Tidy Data Tutor - posit::conf(2023)
Presented by Sean Kross
The data frame is a fundamental data structure for data scientists using Python and R. Pandas and the tidyverse are designed to center building pipelines for the transformation of data frames. However, within these pipelines it is not always clear how each operation is changing the underlying data frame. To explain each step in a pipeline data science instructors resort to hand-drawing diagrams to illustrate the semantics of operations such as filtering, sorting, and grouping.
In this talk, I will introduce Pandas Tutor and Tidy Data Tutor, step-by-step visual representation engines of data frame transformations. Both tools illustrate the row, column, and cell-wise relationships between an operation’s input and output data frames.

Validating and Testing R Dataframes with Pandera via reticulate - R-Python Interoperability
Presented by Niels Bantilan
Original Full Title: Validating and Testing R Dataframes with Pandera via reticulate: A Case Study in R-Python Interoperability
Data science and machine learning practitioners work with data every day to analyze and model them for insights and predictions. A major component of any project is data quality, which is a process of cleaning, and protecting against flaws in data that may invalidate the analysis or model. Pandera is an open source data testing toolkit for dataframes in the Python ecosystem: but can it validate R dataframes?
This talk is composed of three parts: first I’ll describe what data testing is and motivate why you need it. Then, I’ll introduce the iterative process of creating and refining dataframe schemas in Pandera. Finally, I’ll demonstrate how to use it in R with the reticulate package using a simple modeling exercise as an example.

Using R, Python, and Cloud Infrastructure to Battle Aquatic Invasive Species - posit::conf(2023)
Presented by Uli Muellner and Nicholas Snellgrove
Invasive species are a huge threat to lake ecosystems in Minnesota. With over 10,000 water bodies across the state, having up-to-date data and decision support is critical. Researchers at the University of Minnesota have created four complex R and Python models to support lake managers, all pulled together and presented with the most recent infestation data available.
Come along with us to see how we connected these models in the AIS Explorer, a decision support application built in Shiny to help prioritize risks and placing watercraft inspectors, using tools like OCPU and cloud toolings like Lambda, EventBridge and AWS S3.

Using Data to Protect Traditional Lifeways - posit::conf(2023)
Presented by Angie Reed
The spirit of Penobscot Nation’s work to protect the health of their relative, the Penobscot River, is embodied in the Penobscot water song which says ““Water, we love you, thank you so much water, we respect you.”” Because the Penobscot River is not a natural resource - she is a relative, family - this song describes the foundation of our efforts to protect her health and well-being. The identity of Penobscot people cannot be disconnected from the river, and protecting this traditional lifeway is at the heart of our work.
For over a decade we have used R to manage, transform, analyze, and visualize data, and the free, open-source Posit products help us leave a legacy of good data management and the ability to share results with Penobscot Nation citizens. You will learn more about how our use of R has helped us achieve more stringent protections for the Penobscot River and how we engage young people in every step of this work. We are also part of a larger network of tribal environmental professionals, working together to learn R and share data and insights. We will give you information about how you can volunteer to help expand the network of folks providing technical assistance on any R and RStudio related topics.

USGS R Package Development: 10-year Reflections - posit::conf(2023)
Presented by Laura DeCicco
Ten years ago, the first set of git commits was submitted to a new R software package repository “dataRetrieval” with the goal to provide an easy way for R users to retrieve U.S Geological Survey (USGS) water data. At that time, the perception within the USGS was the use of R was exclusive to an elite group of “very serious scientists.” Fast forward, we now find many newer USGS hires having a solid grasp of the language from the start along with the use of R in a wide variety of applications.
In this talk, I’ll discuss my experiences maintaining the dataRetrieval package, how it’s shaped my career, impacted USGS R usage, and why data providers should consider sponsoring their own R packages wrapping their data API services.

Presented by Ryan Timpe
An overview of the benefits unlocked on our data science team by adopting tidymodels.
Data science sure has changed over the past few years! Everyone’s talking about production. RStudio is now Posit. Models are now tidy.
This talk is about embracing that change and updating existing models using the tidymodels framework. I recently completed this change, letting go of our in-production code and revisioning it with tidymodels. My team ended up with a faster, more scalable pipeline that enabled us to better automate our workflow and increase our scale while improving our stakeholders’ experiences.
I’ll share tips and tricks for adopting the tidymodels framework in existing products, best practices for learning and upskilling teams, and advice for using tidymodel packages to build more accessible data science tools.

The Road to Easier Shiny App Deployments - posit::conf(2023)
Presented by Liam Kalita
We’re often helping developers to assess, fix and improve their Shiny apps, and often the first thing we do is see if we can deploy the app. If you can’t deploy your Shiny app, it’s a waste of time. If you can deploy it successfully, then at the very least it runs, so we’ve got something to work with.
There are a bunch of reasons why apps fail to deploy. They can be easy to fix, like Hardcoded secrets, fonts, or missing libraries. Or they can be intractable and super frustrating to deal with, like manifest mismatches, resource starvation, and missing libraries.
At the end of this talk, I want you to know how to identify, investigate and proactively prevent Shiny app deployment failures from happening.

The ‘I’ in Team: Peer-to-Peer Best Practices for Growing Data Science Teams - posit::conf(2023)
Presented by Liz Roten
R users don’t always come in sets. Often, you may be the only user on in the cubicle-block. But, one miraculous day, your manager finally fills the void and you welcome more folks on your team. Suddenly, the little R system you created to suit your needs, like a custom package, code styling, and file organization, isn’t just for you.
Want to suddenly overhaul that one package you wrote two years ago? It probably won’t work when your colleagues try to update it.
Your new teammates are data.table fans, but you prefer the tidyverse. Do you need to refactor? Are style choices, like indentation important when collaborating, or are you just being persnickety?
In this talk, you will learn how to bring new teammates on board and blend your respective styles without pulling your hair out.

Thanks, I Made It with Quartodoc - posit::conf(2023)
Presented by Isabel Zimmerman
When Python package developers create documentation, they typically must choose between mostly auto-generated docs or writing all the docs by hand. This is problematic since effective documentation has a mix of function references, high-level context, examples, and other content.
Quartodoc is a new documentation system that automatically generates Python function references within Quarto websites. This talk will discuss pkgdown’s success in the R ecosystem and how those wins can be replicated in Python with quartodoc examples. Listeners will walk away knowing more about what makes documentation delightful (or painful), when to use quartodoc, and how to use this tool to make docs for a Python package.

Take it in Bits: Using R to Make Eviction Data Accessible to the Legal Aid Community - posit::conf
Presented by Logan Pratico
One in five low-income renter households in the US experienced falling behind on rent or being threatened with eviction in 2021. Yet most are unrepresented when facing eviction in court. The complex and fast-paced legal system obscures access to timely information, leaving tenants without assistance.
In this talk, I discuss the Civil Court Data Initiative’s use of R alongside AWS Cloud and SQL to analyze disaggregate eviction records. I focus on the integration of RMarkdown with Amazon Athena and EC2 to create weekly eviction reports across 20 states for legal aid groups working to assist tenants. The upshot: accessible eviction data to help legal aid providers better address local legal needs.

In this talk we share how good programming practices inspire the way we manage the R-Ladies community in order to make it sustainable.
R-Ladies’ first ten years were about growing the community: from being just one chapter in 2012 to becoming a global organization in 2016, and now fostering more than 230 chapters worldwide. But how can we face the challenges of growing an organization based solely on volunteer work?
In this talk, we discuss how good programming practices –such as modularity, refactoring, and testing– inspire the way we see the sustainable management of an ever-growing community. To that end, we will present our most recent efforts at creating and documenting workflows, distributing the workload, and automating tasks that allow volunteers to focus their time where it is most needed.
After watching this talk, you will get some ideas on how to support volunteers in your own community or project, and on how to use GitHub Actions to automate workflows and tasks.

Succeed in the Life Sciences with R/Python and the Cloud - posit::conf(2023)
Presented by Colby Ford
This talk covers best practices and lessons learned surrounding the use of R and Python by technical teams in the cloud, focusing on Posit Workbench, Azure ML, and Databricks.
In the life sciences, whether it’s pharma, biotech, research, or another type of organization, we are unique in that we blend scientific knowledge with technical skills to extract insights from large, complex datasets. In the cloud, we can architect solutions to help us scale, automate, and collaborate. Interestingly, the use of R and Python by bioinformatics, genomics, biostatistics, and data science teams can be challenging in a cloud-first world where all the data is somewhere other than your laptop (like a data lake).
In this talk, I will share best practices and lessons learned surrounding the use of R and Python by technical teams in the cloud. We’ll focus on the use of Posit Workbench and RStudio on various cloud services such as Azure ML and Databricks.

Styling and Templating Quarto Documents - posit::conf(2023)
Presented by Emil Hvitfeldt
Quarto is a powerful engine to generate documents, slides, books, websites, and more. The default aesthetics looks good, but there are times when you want and need to change how they look. This is that talk.
Whether you want your slides to stand out from the crowd, or you need your documents to fit within your corporate style guide, being able to style Quarto documents is a valuable skill.
Once you have persevered and created the perfect document, you don’t want the effort to go to waste. This is where templating comes in. Quarto makes it super easy to turn a styled document into a template to be used over and over again.

Speeding Up Plots in R/Shiny - posit::conf(2023)
Presented by Ryszard Szymański
A slow plots can ruin the user experience of our dashboard. This talk covers techniques for speeding up the rendering process of our visualisations.
Slow dashboards lead to a poor user experience and cause users to lose interest, or even become frustrated. A common culprit of this situation is a slowly rendering plot.
During the talk, we will dive deeper into how plots are rendered in Shiny, identify common bottlenecks that can occur during the rendering process, and learn various techniques for improving the speed of plots in R/Shiny dashboards.
These techniques will range from more efficient data processing to library-specific optimisations at the browser level.

Solving a Secure Geocoding Problem (That Hardly Anybody Has) - posit::conf(2023)
Presented by Tesla DuBois
Due to data security concerns, the strictest health researchers won’t send patient addresses to remote servers for geocoding. The only existing methods for offline geocoding are expensive, cumbersome, or require working with code - all limiting factors for many researchers. So, a couple of classmates and I made a standalone desktop application using shell, Docker, PostGIS, and Python to geocode addresses through a simple GUI without ever sending them off the local machine. Come for the technical ins and outs and stay for the anecdotes about how my R background played into the daunting, frustrating, but ultimately successful task of creating a data science tool using unfamiliar technologies.

Small Package, Broad Impact: How I Discovered the Ultimate New Hire Hack - posit::conf(2023)
Presented by Trang Le
Onboarding new hires can be a challenging process, but taking a problem-focused approach can make it more meaningful and rewarding. In this talk, I will share how I discovered the ultimate new hire hack by creating two small packages that gave me the confidence I needed when I started at BMS. Through building these packages, I not only learned R things like using bslib and making font files available for published dashboards, but also gained a deep understanding of my company’s internal systems and workflows, and connected with my team via lots of questions. The resulting packages are still heavily used today.
Join me to discover how small packages can have a broad impact and what hiring managers can do to help.

Siuba and duckdb: Analyzing Everything Everywhere All at Once - posit::conf(2023)
Presented by Michael Chow
Every data analysis in Python starts with a big fork in the road: which DataFrame library should I use?
The DataFrame Decision locks you into different methods, with subtly different behavior::
- different table methods (e.g. polars
.with_columns()vs pandas.assign()) - different column methods (e.g. polars
.map_dict()vs pandas.map())
In this talk, I’ll discuss how siuba (a dplyr port to python) combines with duckdb (a crazy powerful sql engine) to provide a unified, dplyr-like interface for analyzing a wide range of data sources‚ whether pandas and polars DataFrames, parquet files in a cloud bucket, or pins on Posit Connect.
Finally, I’ll discuss recent experiments to more tightly integrate siuba and duckdb.

Shiny New Tools for Scaling your Shiny Apps - posit::conf(2023)
Presented by Joe Kirincic
So you have a Shiny app your org loves, but as adoption grows, performance starts getting sluggish. Profiling reveals your cool interactive plots are the culprit. What can you do to make things snappy again? We can increase the number of app instances, sure, but suppose that isn’t an option for us. Another approach is to shift the plotting work from the server onto the client.
In this talk, we’ll learn how to leverage two Javascript projects, DuckDB-WASM and Observable’s Plot.js, in our Shiny app to create fast, flexible interactive visualizations in the browser without burdening our app’s server function. The end result is an app that can scale to more users without needing to increase compute resources.

Presented by Jadey Ryan
Learn how to use R and Quarto parameterized reporting in this four-step workflow to automate custom HTML and Word reports that are thoughtfully designed for audience interpretation and accessibility.
Soil health data are notoriously challenging to tidy and effectively communicate to farmers. We used functional programming with the tidyverse to reproducibly streamline data cleaning and summarization. To improve project outreach, we developed a Quarto project to dynamically create interactive HTML reports and printable PDFs. Custom to every farmer, reports include project goals, measured parameter descriptions, summary statistics, maps, tables, and graphs.
Our case study presents a workflow for data preparation and parameterized reporting, with best practices for effective data visualization, interpretation, and accessibility.

Open Source Solutions to Next-Generation Submissions, After 30 Years of Industry Experience
Presented by Mike K Smith
The pharmaceutical industry is undergoing rapid change, driven by a desire from both industry and regulatory agencies to move to more interactive visualizations and web applications to review data and make decisions. These changes would have been unthinkable 30 years ago when I started working at Pfizer.
In this talk, I’ll consider the drivers for these changes, how open-source tools can help achieve this, and why collaboration across the industry is vital to achieving this goal. I’ll contrast this with my experience of 30 years working in the pharma industry - when the R language had only just been released, when the internet was new, and when submissions to agencies were printed out, loaded onto trucks, and shipped to their doors.

It’s All About Perspective: Making a Case for Generative Art - posit::conf(2023)
Presented by Meghan Santiago Harris
This talk explores how to create art in the R language while highlighting some similarities between the skills required for creating generative art and those needed to perform data science tasks in R.
Because the field of data science is inherently task-oriented, it is no wonder that most people struggle to see the utility of generative art past the bounds of a casual hobby. This talk will invite the participant to learn about generative art while focusing on ““why”” people should create it and its potential place in data science. This talk is suitable for all disciplines and artistic abilities. Furthermore, this talk will aim to expand the participant’s perspective on generative art with the following concepts:
- What is generative art and how can it be created in R or Python
- Justifications for generative art within Data Science
- Examples of programming skills that are transferrable between generative art and pragmatic data science projects

It’s Abstractions All the Way Down… - posit::conf(2023)
Presented by JD Long
Abstractions rule everything around us. JD Long talks about abstractions from the board room to the silicon.
Over 20 years ago Joel Spolsky famously wrote, “All non-trivial abstractions, to some degree, are leaky.” Unsurprisingly this has not changed. However, we have introduced more and more layers of abstraction into our workflows: Virtual Machines, AWS services, WASM, Docker, R, Python, data frames, and on and on. But then on top of the computational abstractions we have people abstractions: managers, colleagues, executives, stakeholders, etc.
JD’s presentation will be a wild romp through the mental models of abstractions and discuss how we, as technical analytical types, can gain skill in traversing abstractions and dealing with leaks.

(Due to unforeseen circumstances, Hadley Wickham presented this talk “slide karaoke” style, from materials prepared by Jenny Bryan.)
In R, the fundamental unit of shareable code is the package. As of March 2023, there were over 19,000 packages available on CRAN. Hadley Wickham and I recently updated the R Packages book for a second edition, which brought home just how much the package development landscape has changed in recent years (for the better!).

For example, maybe each facet represents a city or point on a 2D plane - we’ll explore ways to organize facets in a grid that mimics the data itself - unlocking your ability to explore patterns in 4+ dimensions. Other solutions to this problem rely on manually-curated lists that map common layouts to a grid, but in this talk, we’ll explore solutions that work on EVERYTHING. I’ll show you how to incorporate this technique into your viz and how I built the libraries since there are some interesting data science concepts at play.

Presented by Albert Rapp
You can get the most out of popular R tools by combining them with easy-to-learn HTML & CSS commands.
It’s easy to think that R users do not need HTML and CSS. After all, R is a language designed for data analysis, right? But the reality is that these web standards are everywhere, even in R. In fact, many great tools like {ggtext}, {gt}, {shiny}, and Quarto unlock their full potential when you know a little bit of HTML & CSS. In this talk, I will demonstrate specific examples where R users can benefit from HTML and CSS and show you how to get started with these two languages.

How to Win Friends and Influence People (With Data) - posit::conf(2023)
Presented by Joe Powers
Too many great data science products never go into production. To persuade leaders and colleagues to adopt your data science offering, you must translate your insights into terms that are relevant and accessible to them. Attempts to persuade these audiences with proofs and model performance stats will often fall flat because the audience is left feeling overwhelmed.
This talk will demonstrate the data simulation, visualization, and story-telling techniques that I use to influence leadership and the community-building techniques I use to earn the trust and support of fellow analysts. These efforts were successful in persuading Intuit to adopt advanced analytic methods like sequential analysis that cut the duration of our AB tests by over 60%.

How I Learned to Stop Worrying and Love Public Packages - posit::conf(2023)
Presented by Joe Roberts
The popularity of R and Python for data science is in no small part attributable to the vast collection of extension packages available for everything from common tasks like data cleaning to highly-specialized domain-specific functions. However, with that ease of sharing packages comes a larger target for bad actors trying to exploit them. We’ll explore these security risks along with approaches you can take to mitigate them using Posit Package Manager.

How Data Scientists Broke A/B Testing (And How We Can Fix It) - posit::conf(2023)
Presented by Carl Vogel
As data scientists, we care about making valid statistical inferences from experiments. And we’ve adapted well-established and well-understood statistical methods to help us do so in our A/B tests. Our stakeholders, though, care about making good product decisions efficiently. I’ll describe how the way we design A/B tests can put these goals in tension and why that often causes misalignment between how A/B tests are intended to be used and how they are actually used. I’ll also talk about how I’ve used R to implement alternative experimental approaches that have helped bridge the gap between data scientists and stakeholders.

Github Copilot integration with RStudio, it’s finally here! - posit::conf(2023)
Presented by Tom Mock
This talk closes issue #10148, “Github Copilot integration with RStudio”, the most upvoted feature request in RStudio’s history. Code generating AI tools like Github Copilot‚ promise an “AI pair programmer that offers autocomplete-style suggestions as you code”. For the first time, we’ll show a native integration of Copilot into RStudio, helping to build on that promise by providing AI-generated “ghost text” autocompletion with R and other languages. I’ll also provide a comparison of Copilot’s “ghost text” to a chat-style interface in RStudio via the {chattr} package from the Posit MLVerse team.
To make the most of these new features, I’ll walk through some examples of how sharing additional context, comments, code, and other “prompt engineering” can help you go from code-generating AI tools that feels like an annoying backseat driver to an experienced copilot. We’ll close with a robust end-to-end example of how these new RStudio integrations and packages can help you be a more productive developer.

From Novices to Experts: Building a Community of Engaged R Users - posit::conf(2023)
Presented by Natalia Andriychuk
At Pfizer, we have over 1500 users with R installed on their machines, along with an R community on MS Teams comprising over a thousand colleagues globally. How can we effectively engage with Pfizer R users and celebrate the successes of this community, while sharing best practices? Additionally, how do we avoid isolated groups duplicating efforts to solve R-related problems across different parts of the organization?
To address these challenges, we established the Pfizer R Center of Excellence (CoE) in early 2022. We focus our efforts on bringing together a rapidly growing community of colleagues, providing technical expertise, and offering best-practice guidance. A well-established, maintained and engaged R community promotes an inclusive and supportive learning environment that drives innovation within organizations. Our aim is to help colleagues thrive in their R journey, regardless of their expertise level.
During my talk, I will share the techniques we used to build a supportive R community, the tools employed to increase community engagement, and the successes and challenges encountered in building an engaging community of R users.

This is the story of how a Royal Statistical Society writer discovered Quarto, learned how to code (a bit), and built realworlddatascience.net, an online publication for the data science community.
In March 2022, I was tasked by the Royal Statistical Society with creating a new online publication: a data science website for data science professionals. I’ve been a print journalist for 20 years and have worked on websites in that time, but my coding ability began and ended with wrapping href tags around text and images. That is until I discovered Quarto. In this talk, I describe how I explored, learned, and fell in love with the Quarto publishing system, how I used it to build a website – Real World Data Science (realworlddatascience.net) – and how the open source community mindset helped shape my thinking about what a new publication could and should be!

Dynamic Interactions: webR to Empower Educators & Researchers with Interactive Quarto Docs
Presented by James Balamuta
Full talk title: Dynamic Interactions: Empowering Educators and Researchers with Interactive Quarto Documents Using webR
Traditional Quarto documents often lack interactivity, limiting the ability of students and researchers to fully explore and engage with the presented topic. In this talk, we propose a novel approach that utilizes webR, a WebAssembly-powered version of R, to seamlessly embed R code directly within the browser without the need for a server. We demonstrate how this approach can transform static Quarto documents into dynamic examples by leveraging webR’s capabilities through standard Quarto code cells, enabling real-time execution of R code and dynamic display of results. Our approach empowers educators and researchers alike to harness the power of interactivity and reproducibility for enhanced learning and research experiences.

duckplyr: Tight Integration of duckdb with R and the tidyverse - posit::conf(2023)
Presented by Kirill Müller
The duckplyr R package combines the convenience of dplyr with the performance of DuckDB. Better than dbplyr: Data frame in, data frame out, fully compatible with dplyr.
duckdb is the new high-performance analytical database system that works great with R, Python, and other host systems. dplyr is the grammar of data manipulation in the tidyverse, tightly integrated with R, but it works best for small or medium-sized data. The former has been designed with large or big data in mind, but currently, you need to formulate your queries in SQL.
The new duckplyr package offers the best of both worlds. It transforms a dplyr pipe into a query object that duckdb can execute, using an optimized query plan. It is better than dbplyr because the interface is “data frames in, data frames out”, and no intermediate SQL code is generated.
The talk first presents our results, a bit of the mechanics, and an outlook for this ambitious project.

Diversify Your Career with Shiny for Python - posit::conf(2023)
Presented by Gordon Shotwell
A few years ago my company made a sudden shift from R to Python which was quite bad for my career because I didn’t really know Python. The main issue was that I couldn’t find a niche that allowed me to use my existing knowledge while learning the new language.
Shiny for Python is a great niche for R users because none of the Python web frameworks can do what Shiny can do. Additionally, almost all of your knowledge of the R package is applicable to the Python one.
This talk will provide an overview of the Python web application landscape and articulate what Shiny adds to this landscape, and then go through the five things that R users need to know before developing their first Shiny for Python application.

dbtplyr: Bringing Column-Name Contracts from R to dbt - posit::conf(2023)
Presented by Emily Riederer
starts_with(language): Translating select helpers to dbt. Translating syntax between languages transports concepts across communities. We see a case study of adapting a column-naming workflow from dplyr to dbt’s data engineering toolkit.
dplyr’s select helpers exemplify how the tidyverse uses opinionated design to push users into the pit of success. The ability to efficiently operate on names incentivizes good naming patterns and creates efficiency in data wrangling and validation.
However, in a polyglot world, users may find they must leave the pit when comparable syntactic sugar is not accessible in other languages like Python and SQL.
In this talk, I will explain how dplyr’s select helpers inspired my approach to ‘column name contracts,’ how good naming systems can help supercharge data management with packages like {dplyr} and {pointblank}, and my experience building the {dbtplyr} to port this functionality to dbt for building complex SQL-based data pipelines.

Building a Flexible, Scaleable Self-Serve Reporting System with Shiny - posit::conf(2023)
Presented by Natalie O’Shea
Working in the high-touch world of consulting, our team needed to develop a reporting system that was flexible enough to be tailored to the specific needs of any given partner while still reducing the highly manual nature of populating client-ready slide decks with various metrics and data visualizations. Utilizing the extensive resources developed by the R user community, I was able to create a flexible, scalable reporting system that allows users to populate templated Google slide decks with metrics and professional-grade visualizations using data pulled directly from our database at the time of query. This streamlined approach enables our consultants to spend less time copy-pasting data from one channel to another and instead focus on what they do best: surfacing business-relevant insights and recommendations for our partners.
By sharing my approach to customizable self-serve reporting in Shiny, I hope attendees will walk away with new ideas about how to combine parameterized reporting and dashboard development to get the best of both worlds. Additionally, I hope to end by sharing how this project was pivotal in making the business case for procuring Posit products for my broader organization.

Black Hair and Data Science Have More in Common Than You Think - posit::conf(2023)
Presented by Kari Jordan
Data science is often difficult to define because of its many intersections, including statistics, programming, analytics, and other domain knowledge. Would you believe it if I told you Black hair and data science have much in common?
This talk is for those considering learning about, studying, or pursuing data science. In it, Dr. Kari L. Jordan draws parallels between approaches to caring for Black hair and approaches to learning data science. We start with the roots and end by picking the right tools and products to maintain our coiffure.

Becoming an R Package Author (or How I Got Rich Responding to GitHub Issues) - posit::conf(2023)
Presented by Matt Herman
The transition from analyzing data in R to making packages in R can feel like a big step. Writing code to clean data or make visualizations seems categorically different from building robust “software” on which other people rely.
In this talk, I’ll show why that distinction is not necessarily true by discussing my personal experience from learning R in graduate school to reporting bugs on GitHub to becoming a co-author of the tidycensus package and a practicing data scientist. The positive and supportive R community on GitHub, Twitter, and elsewhere contributes to why anyone who writes R code can become a package author.
- I have not actually gotten rich but I did get freelance data work based on my package contributions!

Automating the Dutch National Flu Surveillance for Pandemic Preparedness - posit::conf(2023)
Presented by Patrick van den Berg
The next pandemic may be caused by a flu strain, and with thousands of patients with the flu in Dutch hospitals annually it is important to have accurate and current data. The National Institute for Public Health and the Environment of the Netherlands (RIVM) collects and processes flu data to achieve pandemic preparedness. However, the flu reporting process used to be very laborious, stealing precious time from epidemiologists. In our journey of automating this data pipeline we learned that collaboration was the most important factor in getting to a working system. This talk will be at the cross-section of data science and epidemiology and will provide you with a valuable opportunity to learn from our experiences.

Adding a Touch of glitr: Developing a Package of Themes on Top of ggplot - posit::conf(2023)
Presented by Aaron Chafetz and Karishma Srikanth Please note, a power issue cut off the first five minutes of the talk.
Explore how our team at the US Agency for International Development (USAID) created our own data viz branding R package on top of ggplot2 and how you can too.
How do you create brand cohesion across your large team when it comes to data viz? Inspired by the BBC’s bbplot, our team at the US Agency for International Development (USAID) developed a package on top of ggplot2 to create a common look and feel for our team’s products. This effort improved not just the cohesiveness of our work, but also trustworthiness. By creating this package, we reduced the reliance on using defaults and the time spent on each project customizing numerous graphic elements. More importantly, this package provided an easier on-ramp for new teammates to adopt R. We share our journey within a federal agency developing a style guide and aim to guide and inspire other organizations who could benefit from developing their own branding package and guidance.

{slushy}: A Bridge to the Future - posit::conf(2023)
Presented by Becca Krouse
Scaling the use of R can present complications for environment management, especially in regulated industries with a focus on traceability. One solution is controlled (aka “frozen”) environments, which are carefully curated and tested by tech teams. However, the speed of R development means the environments quickly become outdated and users are unable to benefit from the latest advances. Enter {slushy}: a team-friendly tool powered by {renv} and Posit Package Manager. Users can quickly mimic a controlled environment, with the easy ability to time travel between snapshot dates. Attendees will learn how {slushy} bolstered our R adoption efforts, and how this strategy enables tech teams and users to work in parallel towards a common future.

How the R for Data Science (R4DS) Online Learning Community Made Me a Better Student - posit::conf
Presented by Lydia Gibson
Through my participation in R4DS Online Learning Community, I have advanced my R and data science skills, making me a better student than I otherwise would have been through just my studies. As a non-traditional MS Statistics student with an undergraduate background in economics, I had absolutely no experience with the R programming language prior to pursuing my Master’s degree. In July 2021, with hopes of getting a headstart on learning R before beginning my degree program, I joined the R4DS Slack Workspace. Along with helping to improve my programming skills, R4DS has connected me with scholarships, mentorship, and other opportunities, and I think that it would be beneficial for other students to know about this great resource.

The workshop will assume some prior experience with Python and Jupyter Notebooks.
Sharing knowledge through writing is a critical aspect of scientific activity, including data science. It allows researchers to communicate their findings and insights to a wider audience, build upon existing work, and collaborate with others in their field. However, until recently, there have been limited options for publishing long-form writing and expository analyses authored in Jupyter Notebooks, a popular medium for data scientists.
Enter Quarto - an innovative, open-source scientific and technical publishing system compatible with Jupyter Notebooks and other popular mediums. Quarto provides data scientists with a seamless way to publish their work in a high-quality format that is easily accessible and shareable. With Quarto, researchers can turn their Jupyter Notebooks into professional-looking publications in a variety of formats, including web pages, books, and slides.
In this workshop, we will demonstrate how Quarto enables data scientists to turn their work products into professional, high-quality publications, websites, blog posts, and other shareable artifacts. As a bonus, we will also discuss how you can create and document Python packages using Jupyter notebooks and Quarto with the help of nbdev.
The learning outcomes for the workshop include: • examine case studies where sharing scientific knowledge has greatly improved the efficacy of data science teams • author documents in plain text markdown or Jupyter notebooks with equations, citations, crossrefs, figure panels, callouts, and advanced layouts • learn how to author content in IPython/Jupyter and the Quarto VS Code extension • leverage Quarto for creating different types of publications, including personal blogs, knowledge management for teams, notes, books, websites, and presentation slides • extend Quarto with notebook filters and extensions • host websites and publications on platforms like GitHub Pages, QuartoPub, and Netlify • test notebooks and documentation with Quarto’s execution options • create and document Python packages with nbdev and Quarto

posit::conf(2023) Workshop: Tidy time series and forecasting in R
Register now: http://pos.it/conf Instructor: Rob J Hyndman Workshop Duration: 2-Day Workshop
This course is for you if you: • already use the tidyverse packages in R such as dplyr, tidyr, tibble and ggplot2 • need to analyze large collections of related time series • would like to learn how to use some tidy tools for time series analysis including visualization, decomposition and forecasting
It is common for organizations to collect huge amounts of data over time, and existing time series analysis tools are not always suitable to handle the scale, frequency and structure of the data collected. In this workshop, we will look at some packages and methods that have been developed to handle the analysis of large collections of time series.
On day 1, we will look at the tsibble data structure for flexibly managing collections of related time series. We will look at how to do data wrangling, data visualizations and exploratory data analysis. We will explore feature-based methods to explore time series data in high dimensions. A similar feature-based approach can be used to identify anomalous time series within a collection of time series, or to cluster or classify time series. Primary packages for day 1 will be tsibble, lubridate and feasts (along with the tidyverse of course).
Day 2 will be about forecasting. We will look at some classical time series models and how they are automated in the fable package, and we will explore the creation of ensemble forecasts and hybrid forecasts. Best practices for evaluating forecast accuracy will also be covered. Finally, we will look at forecast reconciliation, allowing millions of time series to be forecast in a relatively short time while accounting for constraints on how the series are related
posit::conf(2023) Workshop: Teaching Data Science Masterclass
Register now: http://pos.it/conf Instructor: Dr. Mine Çetinkaya-Rundel Workshop Duration: 1-Day Workshop
This course is for you if you: • you want to learn / discuss curriculum, pedagogy, and computing infrastructure design for teaching data science with R and RStudio using the tidyverse and Quarto • you are interested in setting up your class in Posit Cloud • you want to integrate version control with git into your teaching and learn about tools and best practices for running your course on GitHub
This masterclass is aimed primarily at participants teaching data science in an academic setting in semester-long courses, however much of the information and tooling we introduce is applicable for shorter teaching experiences like workshops and bootcamps as well. Basic knowledge of R is assumed and familiarity with the tidyverse and Git is preferred.
There has been significant innovation in introductory statistics and data science courses to equip students with the statistical, computing, and communication skills needed for modern data analysis. Success in data science and statistics is dependent on the development of both analytical and computational skills, and the demand for educators who are proficient at teaching both these skills is growing. The goal of this masterclass is to equip educators with concrete information on content, workflows, and infrastructure for painlessly introducing modern computation with R and RStudio within a data science curriculum. In a nutshell, the day you’ll spend in this workshop will save you endless hours of solo work designing and setting up your course.
Topics will cover teaching the tidyverse in 2023, highlighting updates to R for Data Science (2nd ed) and Data Science in a Box as well as present tooling options and workflows for reproducible authoring, computing infrastructure, version control, and collaboration.
The workshop will be comprised of four modules: • Teaching data science with the tidyverse and Quarto • Teaching data science with Git and GitHub • Organizing, publishing, and sharing of course materials • Computing infrastructure for teaching data science
Throughout each module we’ll shift between the student perspective and the instructor perspective. The activities and demos will be hands-on; attendees will also have the opportunity to exchange ideas and ask questions throughout the session.
In addition to gaining technical knowledge, participants will engage in discussion around the decisions that go into developing a data science curriculum and choosing workflows and infrastructure that best support the curriculum and allow for scalability. We will also discuss best practices for configuring and deploying classroom infrastructures to support these tools
posit::conf(2023) Workshop: Steal like an Rtist: Creative Coding in R
Register now: http://pos.it/conf Instructors: Ijeamaka Anyene Fumagalli & Sharla Gelfand Workshop Duration: 1-Day Workshop
This workshop is for you if you: • are comfortable with R and RStudio, experience with tidyverse and ggplot2 • are interested in applying data visualization skills more creatively, but may not know where to start or how to develop style/inspiration • are an artist interested in exploring code as another medium for creating their work
R is a tool for data analysis but also can be used for self-expression. This workshop will be an introduction to creative coding in R in order to make visual art. We will take an inspiration-first approach, using compelling pieces to discuss and learn the techniques that shape the work. This workshop takes guidance from its namesake, the book “Steal Like An Artist” by Austin Kleon - once we have identified and learned to recreate existing works, we will cover how to take this inspiration and transform, remix, or reinterpret it in the pursuit of developing our own work and artistic styles.
This workshop is hands-on and will cover color theory and manipulation, a reintroduction of the data frame as the foundation for creating art (instead of just for analyzing data!), using ggplot2 as an artistic canvas, creating basic and specialized shapes, tiling and pattern making, developing your own functions and using iteration. We will also discuss how to use controlled randomness to convert a standalone piece into a generative art system that can produce many distinct outputs. Creative coding may seem a world apart from data analysis, but we see a large overlap and intersection of the skills used in both, not to mention the creative muscles that are already used in data visualization

Register now: http://pos.it/conf Instructor: Andy Teucher Workshop Duration: 1-Day Workshop
This workshop is for you if: • You have written several R scripts and find yourself wondering how to reuse or share the code you’ve written • You know how to write functions in R • You are looking for a way to take the next step in your R programming journey
We will be demonstrating some workflows using Git and GitHub. Knowledge of these tools is not required, and you will absolutely be able to complete the workshop without them, but some of the lessons will be more rewarding to you if you are prepared to try them out. If you are looking to get started with Git and GitHub, we recommend you register for the “What they forgot to teach you about R” workshop on Day 1, and join us for this workshop on Day 2.
We are often faced with the need to share our code with others, or find ourselves writing similar code over and over again across different projects. In R, the fundamental unit of reusable code is a package, containing helpful functions, documentation, and sometimes sample data. This workshop will teach you the fundamentals of package development in R, using tools and principles developed and used extensively by the tidyverse team - specifically the ‘devtools’ family of packages including usethis, testthat, and roxygen2. These packages and workflows help you focus on the contents of your package rather than the minutiae of package structure.
You will learn the structure of a package, how to organize your code, and workflows to help you develop your package iteratively. You will learn how to write good documentation so that users can learn how to use your package, and how to use automated testing to ensure it is functioning the way you expect it to, now and into the future. You will also learn how to check your package for common problems, and how to distribute your package for others to use.
This will be an interactive 1-day workshop, and we will be using the RStudio IDE to work through the materials, as it has been designed to work well with the development practices we will be featuring

About the Event#
Shiny makes it easy to build interactive web applications with the power of Python’s data and scientific stack. If you want to develop a python web application you usually need to choose between simple, limited frameworks like Streamlit and more extensible frameworks like Dash. This can cause a lot of problems if you get started with a simple framework but then discover that you need to refactor your application to accommodate the next user request. Shiny for Python differs from other frameworks because it has tremendous range. You can build a small application in a few minutes with the confidence that the framework can handle much more complex problems. In this workshop we will go through the core limitations of Streamlit, and build a Shiny app which avoids those limitations.

Key Resources: ⬡ Get started with {gt} - https://gt.rstudio.com
Reach out: 38:48 - How do I ask Rich about {gt}, feature requests, bug reports, how to solve a problem via {gt}? Rich and the {gt} team would love to hear from you. ⬡ Feature requests & bug reports with GitHub Issues, https://github.com/rstudio/gt/issues ⬡ GitHub Discussions, https://github.com/rstudio/gt/discussions ⬡ Ask the community a question, https://community.rstudio.com/tag/gt ⬡ Follow {gt} on Twitter, feel free to reach out and ask questions, https://twitter.com/gt_package
Timestamps
Rich Iannone Introduction.
03:52 - Why {gt}? - What does {gt} bring to the table? Why so much effort into static, data display tables?
05:50 - Why open source? Why is {gt} open source and why have you dedicated your career to develop open source software?
08:30 - {gt} v0.7.0, Tell us about those new vector formatting functions in {gt}. Why did you include them? Could you show us some examples?
{gt}’s vector formatting functions help you customize the styling, look and feel of your values. Converting the output values R gives you, and making them look exactly the way you want them to can be tricky. A lot of work was put into {gt} to give nice value formatting options. You can now access all these outside of a gt table; e.g. in text, in a plot, etc.
22:35 - Could you provide an example or two with the new styling function called opt_stylize()? What kinds of tables can you make with that? Can you extend that with your own tweaks?
28:15 - Can you make your own themes and share them? “How do I create my own custom theme for my table? A theme I can share with the rest of my organization?”
31:58 - What is the distinction between tab_options and the opt_* functions? Why would a function be in opt_* and not tab_options?
34:00 - sub_values() function, to find and replace certain values in your table.
36:50 - What is the current support for latex in {gt} at the moment? “Personally, I much prefer HTML, but for scientific publications, we are asked to provide a LaTeX file.”
42:50 - “In my work, I often produce A4 output in PDF, mainly with ggplot2 content. It would be nice to be able to combine ggplot + gt tables in a similar way {patchwork} works. Having the plot and the table next to it is very useful sometimes.”
44:30 - Interactive Tables with {gt}?
47:45 - “Any plans to make applying of same style to several columns easier? Unless I’m mistaken, the locations argument of tab_style requires one to specify an individual column. See here: https://gt.rstudio.com/reference/tab_style.html#examples."
Yes, supply a vector of columns or use tidyselect functions.
49:15 - “Excel output with {gt}? Would be a huge improvement. I often have to produce tabular output that can be easily reused. Usually it means Excel tables. So far I have mainly done this with Python and openpyxl or PyWin32 (through COM). A simple solution in R would be great.”
50:20 - Support for additional output formats with {gt}? Excel, PowerPoint, etc.?
50:25 - {pointplank}, a package to methodically validate your data whether in the form of data frames or as database tables., https://rich-iannone.github.io/pointblank/
. Check out the workshop materials at https://github.com/rich-iannone/pointblank-workshop
55:50 - “Are there ways to have grouped rows? I mean when repeated rows have same characters can we merge them to one?”
58:00 - “Is there an ability to add ‘battleship coordinates’ (e.g. column letters & row numbers) to a gt object? This is a standard for table across my org and I’ve been trying to figure out how to implement it.”
59:59 “Do you have suggestions or examples of building out & applying corporate formatting to gt tables (e.g. adding a company logo, company colors, etc.)?”
01:04:30 - “With PDF/LaTeX output for wide tables, it does not shrink the table.”
What’s New in {gt} 0.7.0?
gt 0.7.0 was just released. Rich Iannone, maintainer of gt, dives into the 7 new features added.

00:07 The new Word table output format, .docx output. 00:34 A whole new family of vector formatting functions (vec_fmt_*()) has been added. 01:03 Table presets/themes styling with the new opt_stylize() function. 01:50 The new tab_stub_indent() for superfine control over row label indentation (in the stub) 02:26 The new fmt_duration() function for formatting of time duration values. 03:32 An upgraded gtsave() that uses {webshot2}, .png output looks better. 04:14 Accessibility enhancements for HTML table outputs

Manually testing Shiny applications is often laborious, inconsistent, and doesn’t scale well. Whether you are developing new features, fixing bug(s), or simply upgrading dependencies on a serious app where mistakes have real consequences, it is critical to know when regressions are introduced. shinytest2 provides a streamlined toolkit for unit testing Shiny applications and seamlessly integrates with the popular testthat framework for unit testing R code.
shinytest2 uses chromote to render applications in a headless Chrome browser. chromote allows for a live preview, better debugging tools, and/or simply using modern JavaScript/CSS.
By simply recording your actions as code and extending them to test the more particular aspects of your application, it will result in fewer bugs and more confidence in future Shiny application development.

Rich Iannone || New features in {gt} 0.6.0! || RStudio
00:00 Introduction 00:18 sub_missing() 03:51 Markdown formatting in sub_missing() 04:51 sub_zero() 07:34 sub_small_vals() 13:08 sub_large_vals() 16:25 final thoughts
A new version of the R package {gt} has been released! We are now at version 0.6.0 and there are now even more features that’ll make your display/summary tables look and work much, much better. Let’s run through some of the bigger changes and see the benefits they can bring!
New functions for substituting cell data
We now have four new functions that allow you to make precise substitutions of cell values with perhaps something more meaningful. They all begin with sub_ and that’s short for substitution!
sub_missing() (formerly known as fmt_missing()) Here’s something that’s both old and new. The sub_missing() function (for replacing NAs with… something) is new, but it’s essentially replacing a function that is old (fmt_missing()).
The missing_text replacement of “—” is actually an em dash (the longest of the dash family). This can be downgraded to an en dash with “–” or we can go further with “-”, giving us a hyphen replacement. Or, you can use another piece of text.
If you’re using and loving fmt_missing(), it’s okay! You’ll probably receive a warning about it when you upgrade to {gt} 0.6.0 though. Best to just substitute fmt_missing() with sub_missing() anyway!
sub_zero() The sub_zero() function allows for substituting zero values in the table body.
sub_small_vals() Next up is the sub_small_vals() function. Ever have really, really small values and really just want to say they are small?
With sub_small_vals() we can reformat smaller numbers using the default threshold of 0.01.
Small and negative values can also be handled but they are handled specially by the sign parameter. Setting that to “-” will format only the small, negative values.
You don’t have to settle with the default threshold value or the default replacement pattern (in small_pattern). This can be changed and the “x” in small_pattern (which uses the threshold value) can even be omitted.
sub_large_vals() Okay, there’s one more substitution function to cover, and this one’s for all the large values in your table: sub_large_vals(). With this you can substitute what you might consider as too large values in the table body.
Large negative values can also be handled but they are handled specially by the sign parameter. Setting that to “-” will format only the large values that are negative. You don’t have to settle with the default threshold value or the default replacement pattern (in large_pattern). This can be changed and the “x” in large_pattern (which uses the threshold value) can even be omitted.
Final thoughts We are always trying to improve the gt package with a mix of big features (some examples: improving rendering, adding new families of functions) and numerous tiny features (like improving existing functions, clarifying documentation, etc.). It’s hoped that the things delivered in gt 0.6.0 lead to improvements in how you create and present summary tables in R. If there are features you really want, always feel free to:

Carson Sievert || Customizing Navigation Items in Shiny using {bslib} || RStudio
00:00 Introduction 00:15 Linking inside navbarPage 01:19 Replacing tabPanel with navbarPage, and navbarMenu 02:32 nav_spacer() 03:41 Adding header and//or footer content 04:07 Replacing tabsetPanel with navs_tab and navs_pill 04:32 navs_tab_card() and navs_pill_card() variants 04:40 Demo of all of the nav_*() functions
The bslib R package provides tools for customizing Bootstrap themes directly from R, making it much easier to customize the appearance of Shiny apps & R Markdown documents. bslib’s primary goals are:
- To make custom theming as easy as possible.
- Custom themes may even be created interactively in real-time.
- Also provide easy access to pre-packaged Bootswatch themes.
- Make upgrading from Bootstrap 3 to 4 (and beyond) as seamless as possible. (Shiny and R Markdown default to Bootstrap 3 and will continue to do so to avoid breaking legacy code.)
- Serve as a general foundation for Shiny and R Markdown extension packages. (Extensions such as flexdashboard, pkgdown, and bookdown already fully support bslib’s custom theming capabilities.)

Barret Schloerke || Maximize computing resources using future_promise() || RStudio
00:00 Introduction 01:45 Setting up a multisession using the future package 02:05 Simulation using two workers 04:14 Simulation using 10 workers 05:20 What happens when we run out of workers? 05:35 How Shiny handles future processes like promises 07:16 Introduction to future_promise() 07:45 Demo of the promises package 09:21 Setting the number of workers 10:40 Demo of processing without future_promise() 14:11 Wrapping a slow calculation in a future() 14:53 Demo of processing using Plumber 16:25 Considerations on the number of cores to use 17:21 What happens if we run out of workers? 19:44 Decrease in execution times using future_promise()
In an ideal situation, the number of available future workers (future::nbrOfFreeWorkers()) is always more than the number of future::future() jobs. However, if a future job is attempted when the number of free workers is 0, then future will block the current R session until one becomes available.
The advantage of using future_promise() over future::future() is that even if there aren’t future workers available, the future is scheduled to be done when workers become available via promises. In other words, future_promise() ensures the main R thread isn’t blocked when a future job is requested and can’t immediately perform the work (i.e., the number of jobs exceeds the number of workers).

00:00 Introduction to Reactlog 00:44 Viewing Reactlog using an Old Faithful Shiny app 02:07 The Reactlog interface 04:31 Walking through a reactive graph with Reactlog 05:14 Downstream dependency invalidation in Shiny 06:43 How Shiny “grabs” data 09:41 How the Reactlog timeline works 10:46 Switching between idle states in Reactlog 11:58 Reactlog interactivity - clicking a single item 13:21 Reactlog with the Pythagoras Theorem app 15:45 Adding a UI and server value to add Reactlog to your Shiny app 18:05 Walking through the reactive graph using the Pythagorean Theorem app 21:07 Append-only behavior of Reactlog 21:18 Marking a time point in Reactlog 23:17 Using Reactlog to debug reactivity 26:55 Resetting our app and testing logic changes 28:01 Reactlog with a large Shiny app, CRANwhales 34:10 Freezing reactive values 36:19 Calculating click count in a Shiny app 37:10 Click the button, render the plot is bad - see why
Shiny is an R package from RStudio that makes it incredibly easy to build interactive web applications with R. Behind the scenes, Shiny builds a reactive graph that can quickly become intertwined and difficult to debug. reactlog provides a visual insight into that black box of Shiny reactivity.
After logging the reactive interactions of a Shiny application, reactlog constructs a directed dependency graph of the Shiny’s reactive state at any time point in the record. The reactlog dependency graph provides users with the ability to visually see if reactive elements are:
- Not utilized (never retrieved)
- Over utilized (called independently many times)
- Interacting with unexpected elements
- Invalidating all expected dependencies
- Freezing (and thawing), preventing triggering of future reactivity
There are many subtle features hidden throughout reactlog. Here is a short list quickly describing what is possible within reactlog:
- Display the reactivity dependency graph of your Shiny applications
- Navigate throughout your reactive history to replay element interactions
- Highlight reactive family trees
- Filter on reactive family trees
- Search for reactive elements

Learn more about RStudio Team here. https://www.rstudio.com/products/team/
Find the code for this example here. https://github.com/danielpetzold/space-tracker Read our blog post here. https://www.rstudio.com/blog/build-and-share-jupyter-notebooks-on-rstudio-team/
Timecodes 0:00 - Intro 0:07 - Build Jupyter Notebooks to analyze and visualize data 2:47 - Publish directly from RStudio Workbench to your content hub 5:13 - Share With Your Stakeholders on RStudio Connect
Jupyter Notebooks are interactive documents for code, outputs, and text. However, they’re often stuck in data scientists’ local computing environments. Collaborating can be difficult and sharing can be tedious. To live up to their fullest potential, data science teams need a way to scale their development securely and efficiently — while providing stakeholders easy access to their output and visualizations.
RStudio Team, made up of RStudio Workbench, RStudio Connect, and RStudio Package Manager, brings everything together to help data scientists create, reproduce, and share insights from their Jupyter Notebooks.
Let’s dive into a real-life example by exploring data from NASA’s Center for Near-Earth Objects (NEOs). Daniel Petzold walks us through his data analysis and reporting. Want to explore the report yourself? Check out the published report on RStudio Connect here. https://colorado.rstudio.com/rsc/space-tracker/space_tracker.html
On RStudio Workbench, you have a choice of editors: the RStudio IDE, JupyterLab, Jupyter Notebook, or VS Code. Choose your preference. From here, you can explore your dataset, embed HTML directly in your document, create visualizations, and more.
Once you’ve run your analyses and created insightful visualizations, you want to be able to share them with your team. RStudio Workbench allows you to publish to RStudio Connect, the content platform from RStudio.
You have multiple options: push-button deployment from Jupyter Notebook or using terminal commands from JupyterLab.
It’s not enough to publish your work. Once on RStudio Connect, you can share with end-users. Make your analysis accessible to specific users or more generally with different authentication measures. In addition, you can schedule the document to run at a certain time and send out an email with refreshed data.

With the gt package, anyone can make wonderful-looking tables using the R programming language. The gt philosophy: we can construct a wide variety of useful tables with a cohesive set of table parts. These include the table header, the stub, the column labels and spanner column labels, the table body, and the table footer.
It all begins with table data (be it a tibble or a data frame). You then decide how to compose your gt table with the elements and formatting you need for the task at hand. Finally, the table is rendered by printing it at the console, including it in an R Markdown document, or exporting to a file using gtsave(). Currently, gt supports the HTML, LaTeX, and RTF output formats.
The gt package is designed to be both straightforward yet powerful. The emphasis is on simple functions for the everyday display table needs.

An inclusive solution for teaching and learning R during the COVID pandemic
The COVID pandemic has shaken our teaching and learning approaches in many different ways all over the world.
Nonetheless, it has also provided opportunities for bringing creativity into the classroom.
In this talk, I will discuss how I have used RStudio Cloud in my teaching during the pandemic and how I capitalized on the opportunities that RStudio Cloud offers to deal with the crucial issues of software installation.
Introducing RStudio Cloud in the units has allowed me to work effectively in an online environment to engage, motivate and empower students through their learning process while removing the troubles and hurdles of software installation which is generally particularly challenging in first-year cohorts without prior coding experience.
I used RStudio Cloud in a data science introductory unit at Monash University and as a tool to present the usage of R and RStudio for reproducible reporting in another unit on Reproducible and Collaborative Practises.
In the latter, I introduced RStudio Cloud during the first few weeks to get the students up to speed before transitioning to using R and RStudio Cloud in their own local machines while using the command line interface, Git, and GitHub as a version control tool for reproducible reporting.
I will also discuss how I organized and managed the unit’s RStudio Cloud account so that my research associates were also an integral part of the unit delivery to ensure the success of the units.

Leveraging the Cloud for Analytics Instruction at Scale: Challenges and Opportunities
Data science and programming languages like R and Python are some of the most in demand skills in the world.
Students interested in analytics and professors facilitating curriculums deserve to use industry-leading tools to acquire these skills.
However, it’s challenging to enable this experience in an educational setting, especially at scale.
The traditional tools to facilitate learning analytics simply aren’t great. Students and professors often spend way too much time troubleshooting systems and software, things that are a complete waste of time and detract from the learning experience. Additionally, there are seemingly endless IT hurdles and requirements.
That’s part of the reason we created RStudio Cloud, a brilliantly simple but powerful solution for teaching and learning analytics, especially at scale. RStudio Cloud solves many of the technical and financial challenges associated with teaching analytics. It’s also a joy to use for professors, students, and IT administrators.
In this presentation, Dr. Brian Anderson will discuss the challenges and opportunities associated with leveraging the cloud to deliver analytics instructions at the undergraduate and graduate levels at scale.
Our hope is that you walk away inspired to think about ways you can leverage RStudio and the Cloud to enhance your students’ experiences with learning analytics.

RStudio Cloud | Viewing Learning Work | Instructor View
As an Admin (or Moderator) of your course space, you and your fellow instructors have access to all projects in your space. You can open student projects from any projects listing, or to see all the projects of a given student, go to their profile page by clicking on their name from the Members page.
Note that if you do open a student’s project while they also have it open, they will be temporarily disconnected from the project.
You can also view how much time your students have spent using Cloud. Simply visit the Usage area of your space, where you can see aggregate usage data for the entire class, or for an individual student and their projects.

RStudio Cloud | Tuning Resources | Instructor View
By default, each project is allocated 1 GB of RAM and 1 CPU, and can execute in the background for up to 1 hour. If your plan allows it, you can increase the memory, CPU or background execution time allocated to a project. To do so, open Project settings, go to the Resources panel and adjust the allocation.
Note that copies of a project will inherit its resource settings. However, the effective allocation for the copy will be limited by the maxiumum allowed by the account that “owns” the new copy.
The usage hours consumed by a project in a given amount of time depend on the resources allocated to the project, according to the following formula: (RAM + CPUs allocated) / 2 x hours.
On disk, each project is allocated up to 20GB for its files, data, and packages.
The maximum size of a file that can be uploaded to a project is 500MB.

RStudio Cloud | Troubleshooting | Instructor View
Relaunch Project If you are working on a project, and it fails to load or becomes completely unresponsive, you can relaunch the project. Depending on the underlying problem, relaunching the project may fix it and let you continue.
Allocate Additional Memory memory-gaugeRunning out of memory while working on a project may be the cause of a variety of errors.
The project memory gauge will give you an idea of what percentage of available memory your project is currently using. The gauge updates roughly every ten seconds, so it may not show the exact usage at the current moment. Note that reclaiming unused memory is controlled by R and the operating system - you may see uncanny fluctuations in the gauge as the system manages memory.

RStudio Cloud | Setting Up a Base Project | Instructor View
You can make all projects in a space begin with a default set of files and packages. You do this by defining a Base Project for the space.
Create a new project and add any packages or files you want all projects created in the space to start with. Set the project’s access so that everyone in the space can view the project.
Go to the Space Settings page and select the project as the Base Project. Once you select a project as your Base Project, it will no longer be included in the projects listing for the space. To access it, choose the Edit command from the Space Settings page.
Changes to the Base Project are not retroactive. Changes will not be applied to any projects already created - the changes will only apply to future projects created via the New Project action.

RStudio Cloud | Roles | Instructor View
Each member of a space is assigned a role to determine what they are able to do within the space. The available roles are:
Admin: can manage users, view, edit and manage all projects and view space usage data.
Moderator: can view, edit and manage all projects, and view space usage data.
Contributor: can create, edit and manage their own projects. This is the default.
Viewer: can view projects shared with everyone in the space. A viewer cannot create or save copies of projects.
Members are assigned an initial role when they are invited to or join a space, but roles can be changed by an Admin at any time. When you invite an individual member to a Invitation Required space, you set the initial role in the Add Member dialog box. When someone joins via a sharing link, their initial role is set to the current Initial Role setting in the members options panel. Admins can update a user’s role via the role selector in the members list.
Changing permissions lets you fine-tune the Contributor and Viewer roles. The permissions are:
Contributors can see the members list: enables Contributors to see who can access the space.
Contributors can make their projects visible to all members: enables Contributors to share their projects with everyone in the space.
Contributors can change project resources: enables Contributors to change RAM and CPU settings on their projects.
Viewers can see the members list: enables Viewers to see who can acess the space.

RStudio Cloud | Reusing a Workspace | Instructor View
One approach to reusing a space is to remove the current cohort of students from the space, and reuse the same space with the next cohort. If you are an Admin of a space, you can remove any member from that space.
Go to the Members area of the space. For the member you would like to remove, press the Delete icon. You will be prompted to confirm that you would like to remove them from the space, and to choose whether to leave their projects behind in the space, or move them to their personal space.
You can also remove members programatically via the Cloud API using the rscloud package.
Another option is to create a new space from your current course space using the Copy Space action.
If you’d like to re-use materials from a space, e.g. to teach a new cohort of students, use the Copy Space command. All projects shared with everyone in the original space will be copied over to the new space. Members of the original space are not copied over - you will be the only initial member of the new space.

RStudio Cloud | Project Types | Instructor View
A project is the fundamental unit of work on RStudio Cloud. It encapsulates your R code, packages and data files and provides isolation from other analyses. If you are familiar with projects in the desktop RStudio IDE, an RStudio Cloud project is the same thing, plus some additional metadata for access and sharing.
To create a new project from scratch, simply press the New Project button from the Projects area. Your new project will open in the RStudio IDE.
To create a new project from an existing git repository, press the down arrow on the right side of the New Project button, and choose ‘New Project from Git Repo’ from the menu that appears. Note that your git credentials need to be entered each time you create a new project and are only cached for 15 minutes by default.
To create a Jupyter Project, press the down arrow on the right side of the New Project button, and choose ‘New Jupyter Project’ from the menu that appears.
A new Jupyter project will be created and deployed. Once deployed, you will see the Jupyter hub tree view with a welcome.ipynb notebook that contains information about getting started with Jupyter.

RStudio Cloud | Inviting Co-instructors and Teaching Assistants | Instructor View
After creating a space, go to the Members area to manage its membership. You can add members to your space in three ways:
To add members one by one, choose the Invitation Required option, and send invitations to each person you’d like to add to the space via the Add Member button. Note that for security reasons, the invitation is good for 7 days from the time that it is sent. To allow many people to join the space, choose the Sharing Link option, copy the sharing link and then share that link with all the people you’d like to join the space, either via an email or by posting the link on a web page. Keep in mind that anyone with that link will be able to join your space. If you would like to disable a link you previously shared, choose Reset Sharing Link; this will prevent any additional people from joining the space using that link. Space membership can also be managed programatically. See API Access from R in the Advanced Topics section below for details.
Note that you can switch the access option at any time - a common approach is to initially set the access option to Sharing Link, post the sharing link, then after all the people you want to join the space initially have done so, switch access to Invitation Only. The original sharing link will no longer allow additional people to join the space, but you can add any new members individually.

RStudio Cloud | Invite Learners | Instructor View
As you did to invite your co-instructors, go to the space’s Members area to invite your students to your course space. The easiest approach is to enable access via a sharing link.
- Click on the Sharing link option in the Access section
- Set the Initial Role to Contributor
- Click on the Copy Sharing Link action
You can then distribute the sharing link to all your students via a course web page or email. Once all your students have joined the space, you can either reset the sharing link (which will disable access via the previous sharing link), or set Access to “Invitation Required” to ensure that nobody joins the class later without your permission. See the Members section in Shared Spaces above for more details and alternate methods for adding students to your space.
Note that each student must have their own RStudio Cloud account. When they attempt to access your course space for the first time, they will be prompted to log in, or to sign up for an account if they don’t already have one. If your organization is using SSO, account creation will happen automatically when they log in the first time.
At this point, you and your students should be all set.

RStudio Cloud | Creating an Assignment | Instructor View
A good way to create assignments for your students is to make a project for each assignment, and populate it with the files and packages you would like each student to have when they begin the assignment. When you are ready to reveal an assignment to your students, open the project and do the following:
- Click on the Project Settings button (the gear in the upper right)
- Select the Access panel
- Set the project access so it can be viewed by everyone in the space
- Check “Make this project an assignment”
When the student opens an assignment project (either via the projects listing, or via a direct link to the project), RStudio Cloud will automatically make a copy for them. To convey this special behavior, assignments are displayed a bit differently, both for you and for your students.
You can see the students’ copies of the assignment by clicking on the “View n derived projects” link that will appear with your original project.
Note that changes you make to the original assignment will not be applied to any student copies already created. The changes will only apply to future copies of the assignment.

Nicolas Nguyen - ZEISS | Supply Chain Management Meetup | RStudio
0 - 50:20 Presentation 50:20 - 56:52 Q&A Presentation by Nicolas Nguyen, Digital Supply Chain and Global S&OP Leader for Carl Zeiss Meditec
Abstract: In demand & supply planning, we often need to calculate projected inventories and replenishment plans - sometimes for hundreds or thousands of SKUs, and through different levels of the distribution network.
In the sales & operations planning (S&OP) process, we might need to run some scenarios to balance demand and supply to support sales: changing inventories plans, sales plans, delivery lead times, production plans, product mix, etc.
Using Shiny, we can design simple, powerful, scalable, and reproducible apps for demand & supply planning as well as the S&OP process. In this talk, you will learn about real-life examples of web applications, which can be deployed in a few minutes to perform some popular demand & supply planning operations.
__
Thank you to Nicolas for an awesome presentation on how he is using Shiny today. With all the interest from the community in this topic, we’d love to continue the discussion and connect us all through:

West Virginia leading nation at start of vaccine rollout: https://www.vox.com/first-person/2021/3/4/22313540/covid-19-vaccine-west-virginia
In the United States, approximately 2.5 million doses of COVID vaccines are being delivered each day, and how these doses go from the manufacturer to a shot in someone’s arm varies by state, often with mixed results.
But early on in the vaccine distribution process, one state led the pack in terms of using the majority of vaccine doses it had been allotted. That state? West Virginia.
Part of what has made West Virginia successful is the creation of an inventory management system using Shiny, an open source framework for building interactive web applications. The system was built by Data Driven West Virginia, part of the John Chambers College of Business and Economics at West Virginia University, in collaboration with the West Virginia Army National Guard.
Using Shiny has provided visibility into each component of the vaccine supply chain, leading to the creation of distribution plans that are able to quickly and efficiently match supply with demand, getting vaccines to the right people in the right location at the right time.
RStudio’s mission is to create free and open-source software for data science, scientific research, and technical communication to enhance the production and consumption of knowledge by everyone, regardless of economic means, and to facilitate collaboration and reproducible research, both of which are critical to the integrity and efficacy of work across industries.

To understand just how hard it is to get vaccines to the population, it helps to understand where it can go wrong. This starts with how vaccines are packed into containers.
To fill up a container, Pfizer places 195 vials into a tray, and up to 5 trays into a single container. Moderna puts 10 vials into a small box, and then combines a minimum of 10 small boxes into a single container. In most states Pfizer and Moderna ship directly to the organization that will be administering the vaccine to the population. This could be a hospital, a pharmacy, or any place where trained professionals will be putting shots into arms.
But what happens when a pharmacy receives a full container from Pfizer, 975 vials, but only needs 600?
West Virginia has removed this complication by shipping directly to five hubs strategically located throughout the state. Within each of these hubs, containers of vaccine vials are broken down into smaller components and then either picked up or shipped directly to the hospital, pharmacy, or organization that will be administering the vaccine.
These hubs are managed by the Joint Interagency Task Force (JIATF), a team of teams composed of public, private, and governmental organizations as well as the National Guard. The Joint Interagency Task Force is responsible for drawing up a weekly distribution plan for each hub, in alignment with CDC allocations, and matching vaccine supply with demand.
By using a statewide system managed by a central organization, there’s a level of agility and fluidity that allows each hub to adjust to a variety of changes in order to maximize the number of vaccines that are being administered to the population each week.

Webinar Summary | Avoid Dashboard Fatigue | RStudio (2020)
0:00 Introduction 0:07 The Problem 1:05 The Solution 3:20 Real Life Success Stories 5:27 Demo (with code)
Don’t have an hour to watch a webinar? We’ve made a summary video that covers the main points of our “Avoid Dashboard Fatigue” webinar from Sean Lopp and Rich Iannone.
The full webinar covered: Data science teams face a challenging task. Not only do they have to gain insight from data, they also have to persuade others to make decisions based on those insights. To close this gap, teams rely on tools like dashboards, apps, and APIs. But unfortunately data organizations can suffer from their own success - how many of those dashboards are viewed once and forgotten? Is a dashboard of dashboards really the right solution? And what about that pesky, precisely formatted Excel spreadsheet finance still wants every week?
In this webinar, we’ll show you an easy way teams can solve these problems using proactive email notifications through the blastula and gt packages, and how RStudio pro products can be used to scale out those solutions for enterprise applications. Dynamic emails are a powerful way to meet decision makers where they live - their inbox - while displaying exactly the results needed to influence decision-making. Best of all, these notifications are crafted with code, ensuring your work is still reproducible, durable, and credible.

Jenny Bryan | Help me help you: creating reproducible examples | RStudio (2018)
What is a reprex? It’s a reproducible example. Making a great reprex is both an art and a science and this webinar will cover both aspects. A reprex makes a conversation about code more efficient and pleasant for all. This comes up whenever you ask someone for help, report a bug in software, or propose a new feature. The reprex package (https://reprex.Tidyverse.org ) makes it especially easy to prepare R code as a reprex, in order to share on sites such as https://community.rstudio.com , https://github.com , or https://stackoverflow.com . The habit of making little, rigorous, self-contained examples also has the great side effect of making you think more clearly about your programming problems.

Hadley Wickham | testthat 3.0.0 | RStudio (2020)
In this webinar, I’ll introduce some of the major changes coming in testthat 3.0.0. The biggest new idea in testthat 3.0.0 is the idea of an edition. You must deliberately choose to use the 3rd edition, which allows us to make breaking changes without breaking old packages. testthat 3e deprecates a number of older functions that we no longer believe are a good idea, and tweaks the behaviour of expect_equal() and expect_identical() to give considerably more informative output (using the new waldo package).
testthat 3e also introduces the idea of snapshot tests which record expected value in external files, rather than in code. This makes them particularly well suited to testing user output and complex objects. I’ll show off the main advantages of snapshot testing, and why it’s better than our previous approaches of verify_output() and expect_known_output().
Finally, I’ll go over a bunch of smaller quality-of-life improvements, including tweaks to test reporting and improvements to expect_error(), expect_warning() and expect_message().

Roche & Novartis: Effective Visualizations for Data Driven Decisions || Posit (2020)
Effective visual communication is a core task for all data scientists including statisticians, epidemiologists, machine learning experts, bioinformaticians, etc.
By using the right graphical principles, we can better understand data, highlight core insights and influence decisions toward appropriate actions. Without it, we can fool ourselves and others and pave the way to wrong conclusions and actions. While numerous solutions exist to analyze data, these often require many manual steps to convert them into visually convincing and meaningful reports. How do we put this in practice in an accurate, transparent and reproducible way?
In this webinar we will introduce an open collaborative effort, currently undertaken by Roche and Novartis, to develop solutions for effective visual communication with a focus on reporting medical and clinical data. The aim of the collaboration is to develop a user-friendly, fit for purpose, open source package to simplify the use of good graphical principles for effective visual communication of typical analyses of interventional and observational data encountered in clinical drug development. We will introduce the initial visR package design which easily integrates into a typical tidyverse workflow. The package provides guidance and meaningful default parameters covering all aspects from the design, implementation and review of statistical graphics.

Sean Lopp & Lou Bajuk | R & Python: A Data Science Love Story | RStudio (2020)
Many Data Science teams today leverage both R and Python in their work, but struggle to use them together. Data Science leaders and their business partners find it difficult to make key data science content easily discoverable and available for decision-making, while IT Admins and DevOps engineers grapple with how to efficiently support these teams without duplicating infrastructure. Even experienced data scientists familiar with both languages often struggle to combine them without painful context switching and manual translations.
In this webinar, you will learn how RStudio helps organizations tackle these challenges, with a focus on some of the recent additions to our products that have helped deepen the happy relationship between R and Python:
- Easily combine R and Python in a single Data Science project using a single IDE.
- Leverage a single infrastructure to launch and manage Jupyter Notebooks, JupyterLab, VSCode and the RStudio IDE, while giving your team easy access to Kubernetes and other resources.
- Share and manage access to R- and Python-based interactive applications, dashboards, and APIs, all in a single place.

Sean Lopp & Rich Iannone | Avoid Dashboard Fatigue | RStudio (2020)
Data science teams face a challenging task. Not only do they have to gain insight from data, they also have to persuade others to make decisions based on those insights. To close this gap, teams rely on tools like dashboards, apps, and APIs. But unfortunately data organizations can suffer from their own success - how many of those dashboards are viewed once and forgotten? Is a dashboard of dashboards really the right solution? And what about that pesky, precisely formatted Excel spreadsheet finance still wants every week?
In this webinar, we’ll show you an easy way teams can solve these problems using proactive email notifications through the blastula and gt packages, and how RStudio pro products can be used to scale out those solutions for enterprise applications. Dynamic emails are a powerful way to meet decision makers where they live - their inbox - while displaying exactly the results needed to influence decision-making. Best of all, these notifications are crafted with code, ensuring your work is still reproducible, durable, and credible.
We’ll demonstrate how this approach provides solutions for data quality monitoring, detecting and alerting on anomalies, and can even automate routine (but precisely formatted) KPI reporting.

Marie Vendettuoli | Lessons learned developing a library of validated packages | RStudio
Full title: Towards an integrated {verse}: lessons learned developing a library of validated packages
Developing R packages as a unified {verse} – a set of packages that work well together but with each focusing on individual tasks – is an efficient strategy to structure support for complex workflows. The ongoing challenge becomes managing the growth of related packages in a holistic manner. This is especially problematic in industries with a heavy emphasis on stability, for example if packages need to be validated prior to use in production. In this talk, I will discuss a paradigm for developing and maintaining validated R packages, emphasizing the following areas:
- Strategies for organizing packages to prevent excessive re-work
- Facilitating responsive, iterative development and
- Empathy for developer and user experiences

The rKenyaCensus package contains the results of the 2019 Kenya Population Census. The census exercise was carried out in August 2019, and the results were released in February 2020. Kenya leveraged on technology to capture data during cartographic mapping, enumeration and data transmission, making the 2019 Census the first paperless census to be conducted in Kenya. The data was published in four different pdf files (Volume 1 - Volume 4) which can be found in the Kenya National Bureau of statistics website. The data in its current form was open and accessible, but not usable and so there was need to convert it into a machine readable format. This data can be used by the government, non-governmental organizations and any other entities for data driven policy making and development. During the talk, I will explain the reasons behind development of the package, take you through the steps I took during the process and finally showcase analysis of certain aspects of the data.

Nicole Kramer | A New Paradigm for Multifigure Coordinate-Based Plotting in R | RStudio
R is unparalleled in its ability to transform raw data into a wide array of beautiful graphics, all within the same environment. However, when it comes to complex, multi-paneled plots, users rely on 3rd party graphic design software to arrange plots. Here I present the new world of programmatic, coordinate-based multi-figure plotting in R. Employing grid Graphics and drawing from the paradigms of base plotting and ggplot2, I am developing a package that will revolutionize the way plots are laid out in R. Not only will individual plots be aesthetically customizable and tailored for speed, users will also be offered exquisite control over all aspects of page layout, plot placement, and arrangements. Come join me in changing how we plot in R!

Megan Beckett | Aesthetically automated figure production | RStudio
Automation, reproducibility, data driven. These are not normally concepts one would associate with the traditional publishing industry, where designers normally manually produce every artefact in proprietary software. And, when you have 1000s of figures to produce and update for a single textbook, this becomes an insurmountable task, meaning our textbooks quickly become outdated, especially in our rapidly advancing world.
With R and the tidyverse in our back pocket, we rose to the challenge to revolutionize this workflow. I will explain how we collaborated with a publishing group to develop a system to aesthetically automate the production of figures for a textbook including translations into several languages.
I think you’ll find this talk interesting as it shows how we applied tools that are familiar to us, but in an unconventional way to fundamentally transform a conventional process.
About Megan: Megan Beckett is a Data Scientist at Exegetic Analytics, where she consults, develops and leads several analytical projects across a wide range of fields and industries. “Scientifically creative; creatively scientific.” This aptly describes her philosophy and approach in her work and life.

She loves to paint, with her most recent work exploring the biodiversity of southern Africa , and running is her passion, whether on the road or the trail
Matt Thomas & Mike Page | How the Tidyverse helped the British Red Cross respond to COVID | RStudio
Full title: Cognitive speed: How the Tidyverse helped the British Red Cross respond quickly to COVID-19
We will discuss the importance of cognitive speed, defined here as the rate in which an idea can be translated into code, and why the Tidyverse excels in this domain. We will demonstrate this idea in relation to a suite of tools we were required to rapidly develop at the British Red Cross in order to respond effectively to the COVID-19 pandemic. To do this, we will exhibit how elements of the unifying design principles outlined in the ‘tidyverse design guide - Tidyverse team’ relate to the notion of cognitive speed, giving specific examples for various design considerations. We believe this talk will encourage reflection on better design practices for future R developers, using the design principles of the tidyverse as the guiding beacon.
About Matt: Dr. Matt Thomas is Head of Strategic Insight and Foresight at the British Red Cross. Matt’s team aims to help the Red Cross become more anticipatory and proactive by producing insights and tools including the Vulnerability Index (https://britishredcrosssociety.github.io/covid-19-vulnerability/ ) and Resilience Index (https://britishredcross.shinyapps.io/resilience-index/) .

Ahmadou Dicko | Humanitarian Data Science with R | RStudio
Humanitarian actors are increasingly using data to drive their decisions. Since the Haiti 2010 earthquake, the volume of data collected and used by humanitarians has been growing exponentially and organizations are now relying on data specialists to turn all this data into life-saving data products.
These data products are created by teams using proprietary point and click software. The process from the raw data to the final data product involves a lot of clicking, copying and pasting and is usually not reproducible.
Another approach to humanitarian data science is possible using R. In this talk, I will show how to seamlessly develop reproducible, reusable humanitarian data products using the tidyverse, rmarkdown and some domain-focused R packages.
About Ahmadou: Ahmadou Dicko is a statistics and data analysis officer at the United Nations High Commissioner for Refugees (UNHCR) where he uses statistics and data science to help safeguard the rights and well-being of refugees in West and Central Africa. He has an extensive experience in the use of statistics and data science in development and humanitarian projects. Ahmadou was the lead of the OCHA Center for Humanitarian Data team for West and Central Africa and has worked with several humanitarian and development organizations such as IFRC, FAO, IAEA, OCHA. Ahmadou is a RStudio trainer (https://education.rstudio.com/trainers/ ) and he is passionate about the R community. He is currently co-organizing the Dakar R User Group (https://www.meetup.com/DakaR-R-User-Group/ ) and co-leading the AfricaR initiative (https://africa-r.org/ )

Jake Thompson | Branding and Packaging Reports with R Markdown | RStudio (2020)
The creation of research reports and manuscripts is a critical aspect of the work conducted by organizations and individual researchers. Most often, this process involves copying and pasting output from many different analyses into a separate document. Especially in organizations that produce annual reports for repeated analyses, this process can also involve applying incremental updates to annual reports. It is important to ensure that all relevant tables, figures, and numbers within the text are updated appropriately. Done manually, these processes are often error prone and inefficient. R Markdown is ideally suited to support these tasks. With R Markdown, users are able to conduct analyses directly in the document or read in output from a separate analyses pipeline. Tables, figures, and in-line results can then be dynamically populated and automatically numbered to ensure that everything is correctly updated when new data is provided. Additionally, the appearance of documents rendered with R Markdown can be customized to meet specific branding and formatting requirements of organizations and journals. In this presentation, we will present one implementation of customized R Markdown reports used for Accessible Teaching, Learning, and Assessment Systems (ATLAS) at the University of Kansas. A publicly available R package, ratlas, provides both Microsoft Word and LaTeX templates for different types of projects at ATLAS with their own unique formatting requirements. We will discuss how to create brand-specific templates, as well as how to incorporate the templates into an R package that can be used to unify report creation across an organization. We will also describe other components of branding reports beyond R Markdown templates, including customized ggplot2 themes, which can also be wrapped into the R package. Finally, we will share lessons learned from incorporating the R package workflow into an existing reporting pipeline. https://rstudio.com/resources/rstudioconf-2020/branding-and-packaging-reports-with-r-markdown/
Joe Cheng | Styling Shiny apps with Sass and Bootstrap 4 | Posit (2020)
Customizing the style–fonts, colors, margins, spacing–of Shiny apps has always been possible, but never as easy as we’d like it to be. Canned themes like those in the shinythemes package can easily make apps look slightly less generic, but that’s small consolation if your goal is to match the visual style of your university, corporation, or client.
In theory, one can “just” use CSS to customize the appearance of your Shiny app, the same as any other web application. But in practice, the use of large CSS frameworks like Bootstrap means significant CSS expertise is required to comprehensively change the look of an app.
Relief is on the way. As part of a round of upgrades to Shiny’s UI, we’ve made fundamental changes to the way R users can interact with CSS, using new R packages we’ve created around Sass and Bootstrap 4. In this talk, we’ll show some of the features of these packages and tell you how you can take advantage of them in your apps.

Yihui Xie | One R Markdown Document, Fourteen Demos | RStudio (2020)
R Markdown is a document format based on the R language and Markdown to intermingle computing with narratives in the same document. With this simple format, you can actually do a lot of things. For example, you can generate reports dynamically (no need to cut-and-paste any results because all results can be dynamically generated from R), write papers and books, create websites, and make presentations. In this talk, I’ll use a single R Markdown document to give demos of the R packages rmarkdown,
- bookdown for authoring books (https://bookdown.org ),
- blogdown for creating websites (https://github.com/rstudio/blogdown) ,

Amelia McNamara | Working with categorical data in R without losing your mind | RStudio (2019)
Categorical data, called “factor” data in R, presents unique challenges in data wrangling. R users often look down at tools like Excel for automatically coercing variables to incorrect datatypes, but factor data in R can produce very similar issues. The stringsAsFactors=HELLNO movement and standard tidyverse defaults have moved us away from the use of factors, but they are sometimes still necessary for analysis. This talk will outline common problems arising from categorical variable transformations in R, and show strategies to avoid them, using both base R and the tidyverse (particularly, dplyr and forcats functions).

Emily Robinson | Building an AB testing analytics system with R and Shiny | RStudio (2019)
Online experimentation, or A/B Testing, is the gold standard for measuring the effectiveness of changes to a website. While A/B testing is used at tens of thousands of companies, it can seem difficult to parse without resorting to expensive end-to-end commercial options. Using DataCamp’s system as an example, I’ll illustrate how R is actually a great language for building powerful analytical and visualization A/B testing tools. We’ll first dive into our open-source funneljoin package, which allows you to quickly analyze sequential actions using different types of behavioral funnels. We’ll then cover the importance of setting up health checks for every experiment. Finally, we’ll see how Shiny dashboards can help people monitor and quickly analyze multiple A/B tests each week.

Hilary Parker | Cultivating creativity in data work | RStudio (2019)
Traditionally, statistical training has focused primarily on mathematical derivations, proofs of statistical tests, and the general correctness of what methods to use for certain applications. However, this is only one dimension of the practice of doing analysis. Other dimensions include the technical mastery of a language and tooling system, and most importantly the construction of a convincing narrative tailored to a specific audience, with the ultimate goal of them accepting the analysis. These “softer” aspects of analysis are difficult to teach, perhaps more so when the field is framed as mathematics and often housed in mathematics departments. In this talk, I discuss an alternative framework for viewing the field, borrowing upon the past work in other fields such as design. Looking forward, we as a field can borrow from these fields to cultivate and hone the creative lens so necessary to the success of applied work.

Angela Bassa | Data science as a team sport | RStudio (2019)
How do you data science as a team sport? Oftentimes a data scientific initiative starts with just a single, lonesome data scientist. But when that germ of a team is successful and starts expanding, should the team be embedded in other disciplines or should it be centralized into its own function? Where should it live in the organizational structure? Should you focus on recruiting senior data scientists or is there a benefit to attracting junior talent as well? And in terms of capabilities, should you hold out for unicorns or hire several specialists to get all jobs done? Data scientists need to work on almost every aspect of a business, so how should a team composition set the data science discipline up for success? Great data scientists have career options and won’t abide bad managers for very long: if you want to retain them, you’ll need to care about their work, connect it to the business, and design a diverse, resilient, high-performing team.

Eric Nantz | Effective use of Shiny modules in application development | RStudio (2019)
As a Shiny application grows in scale, organizing code into reusable and streamlined components becomes vital to manage future enhancements and avoid unnecessary duplication. Shiny modules are customized R functions that are easily reused multiple times within an application by avoiding namespace collisions and assist with organizing the code base. Like R functions, modules can be simple utilities or elaborate pieces with multiple inputs and outputs. While the process of creating a module is uncomplicated, application developers can quickly encounter challenges including communication among modules, defining logical compositions, and avoiding hidden state modifications. In this talk, we will introduce practical principles and techniques developers can leverage to address these issues head-on such as documenting modules, passing parameters and return values effectively between modules, and how nesting modules enables dynamic user interfaces with minimal overhead.

Much of my current work involves a combination of data acquisition, statistical programming, tools development, and visualizing the results. I love creating software that helps people accomplish things. I regularly update several R package projects (all available on GitHub). One such package is called DiagrammeR and it’s great for creating network graphs and performing analyses on the graphs. One of the big draws for open-source development is the collaboration that comes with the process. I encourage anyone interested to ask questions, make recommendations, or even help out if so inclined!
Jim Hester | It depends: A dialog about dependencies | RStudio (2019)
Software dependencies can often be a double-edged sword. On one hand, they let you take advantage of others’ work, giving your software marvelous new features and reducing bugs. On the other hand, they can change, causing your software to break unexpectedly and increasing your maintenance burden. These problems occur everywhere, in R scripts, R packages, Shiny applications and deployed ML pipelines. So when should you take a dependency and when should you avoid them? Well, it depends! This talk will show ways to weigh the pros and cons of a given dependency and provide tools for calculating the weights for your project. It will also provide strategies for dealing with dependency changes, and if needed, removing them. We will demonstrate these techniques with some real-life cases from packages in the tidyverse and r-lib.

Jenny Bryan | Lazy evaluation | RStudio (2019)
The “tidy eval” framework is implemented in the rlang package and is rolling out in packages across the tidyverse and beyond. There is a lively conversation these days, as people come to terms with tidy eval and share their struggles and successes with the community. Why is this such a big deal? For starters, never before have so many people engaged with R’s lazy evaluation model and been encouraged and/or required to manipulate it. I’ll cover some background fundamentals that provide the rationale for tidy eval and that equip you to get the most from other talks.

Jesse Sadler | Learning and using the tidyverse for historical research | RStudio (2019)
My talk will discuss how R, the tidyverse, and the community around R helped me to learn to code and create my first R package. My positive experiences with the resources for learning R and the community itself led me to create a blog detailing my experiences with R as a way to pass along the knowledge that I gained. The next step was to develop my first package. The debkeepr package integrates non-decimal monetary systems of pounds, shillings, and pence into R, making it possible to accurately analyze and visualize historical account books. It is my hope that debkeepr can help bring to light crucial and interesting social interactions that are buried in economic manuscripts, making these stories accessible to a wider audience.

I received a Ph.D. in European History from UCLA in 2015 and have taught courses on cultural and intellectual history of early modern Europe and the Atlantic. My research investigates the familial basis of the early modern capitalism through archival research on two mercantile families from Antwerp at the end of the sixteenth and beginning of the seventeenth century. I am currently working on a manuscript that argues for the significance of sibling relationships and inheritance in the development of early modern trade. My manuscript places concepts such as patriarchy, emotion, exile, and friendship at the heart of the efficacy of long-distance trade networks and the growth of capitalism
Miles McBain | Our colour of magic The open sourcery of fantastic R packages | RStudio (2019)
What does it mean to say software is, to quote one Twitter user, ‘so f***ing magical!’? In the context of our popular community hobby of rating and sharing R packages, the term ‘magic’ seems reserved for our most powerful expressions of visceral approval. Why is this? And what does it say about how we value software? Can this magical quality be quantified? We will consider these questions in examination of magical specimens, and in the process reveal the surprising depths at which notions of magic are embedded in the R zeitgiest.

Garrett Grolemund | R Markdown The bigger picture | RStudio (2019)
Statistics has made science resemble math, so much so that we’ve begun to conflate p-values with mathematical proofs. We need to return to evaluating a scientific discovery by its reproducibility, which will require a change in how we report scientific results. This change will be a windfall to commercial data scientists because reproducible means repeatable, automatable, parameterizable, and schedulable.

Karl Broman | R qtl2 Rewrite of a very old R package | RStudio (2019)
For nearly 20 years, I’ve been developing, maintaining, and supporting an R package, R/qtl, for mapping quantitative trait loci (genetic loci that contribute to variation in quantitative traits, such as blood pressure) in experimental crosses (such as in mice). It’s a rather large package, with 39k lines of R code, 24k lines of C code, and nearly 300 user-accessible functions. In the past several years, I’ve been working on rewriting the package, to better handle high-dimensional data and more complex experimental crosses. This has been a good opportunity to take advantage of many new tools, including Rcpp, Roxygen2, and testthat. I’ll describe my efforts to avoid repeating the mistakes I made the first time around.

Alex Hayes | Solving the model representation problem with broom | RStudio (2019)
The R objects used to represent model fits are notoriously inconsistent, making data analysis inconvenient and frustrating. The broom package resolves this issue by defining a consistent way to represent model fits. By summarizing essential information about fits in tidy tibbles, broom makes it easy to programmatically work with model objects. Combining broom with list-columns results in an especially powerful way to work with many model fits at once. This talk will feature several case studies demonstrating how broom resolves common problems in data analysis

Edzer Pebesma | Spatial data science in the Tidyverse | RStudio (2019)
Package sf (simple feature) and ggplot2::geom_sf have caused a fast uptake of tidy spatial data analysis by data scientists. Important spatial data science challenges are not handled by them, including raster and vector data cubes (e.g. socio-economic time series, satellite imagery, weather forecast or climate predictions data), and out-of-memory datasets. Powerful methods to analyse such datasets have been developed in packages stars (spatiotemporal tidy arrays) and tidync (tidy analysis of NetCDF files). This talk discusses how the simple feature and tidy data frameworks are extended to handle these challenging data types, and shows how R can be used for out-of-memory spatial and spatiotemporal datasets using tidy concepts.

Irene Steves | Teaching data science with puzzles | RStudio (2019)
Of the many coding puzzles on the web, few focus on the programming skills needed for handling untidy data. During my summer internship at RStudio, I worked with Jenny Bryan to develop a series of data science puzzles known as the “Tidies of March.” These puzzles isolate data wrangling tasks into bite-sized pieces to nurture core data science skills such as importing, reshaping, and summarizing data. We also provide access to puzzles and puzzle data directly in R through an accompanying Tidies of March package. I will show how this package models best practices for both data wrangling and project management.

Nic Crane | The future’s Shiny: Pioneering genomic medicine in R | Posit (2019)
Shiny’s expanding capabilities are rapidly transforming how it is used in an enterprise. This talk details the creation of a large-scale application, supporting hundreds of concurrent users, making use of the future and promises packages. The 100,000 genomes project is an ambitious exercise that follows on from the Human Genome Project - aiming to put the UK at the forefront of genomic medicine, with the NHS as the first health service in the world to offer precision medicine to patients with rare diseases and cancer. Data is at the heart of this project; not only the outputs of the genomic sequencing, but vast amounts of metadata used to track progress against the 100,000 genome target and the status and path of each case through the sample tracking pipeline. In order to make this data readily available to stakeholders, Shiny was used to create an application containing multiple interactive dashboards. A scaled-up version of the app is being rolled out in early 2019 to a much larger audience to support the National Genomics Informatics Service, with the challenge of creating a complex app capable of supporting so many users without grinding to a halt. In this talk, I will explain why Shiny was the obvious technology choice for this task, and discuss the design decisions which enabled this project’s success.

David Robinson | The unreasonable effectiveness of public work | RStudio (2019)
In this talk, I’ll lay out the reasons that blogging, open source contribution, and other forms of public work are a critical part of a data science career. For beginners, a blog is a great accompaniment to data science coursework and tutorials, since it gives you experience applying practical data science skills to real problems. For data scientists at any stage of their careers, open source development offers practice in collaboration, documentation, and interface design that complement other kinds of software development. And for data scientists more advanced in their careers, writing a book is a great way to crystallize your expertise and ensure others can build on it. All of these practices build skills in communication and collaboration that form an essential component of data science work. Each also lets you build a public portfolio of your skills, get feedback from your peers, and network with the larger data science community.

Earo Wang | Melt the clock Tidy time series analysis | RStudio (2019)
Time series can be frustrating to work with, particularly when processing raw data into model-ready data. This work presents two new packages that address a gap in existing methodology for time series analysis (raised in rstudio::conf 2018). The tsibble package supports organizing and manipulating modern time series, leveraging tidy data principles along with contextual semantics: index and key. The tsibble data structure seamlessly flows into forecasting routines. The fable package is a tidy renovation of the forecast package. It promotes transparent forecasting practices and concise model representations, to empower analysts tackling a broad domain of forecasting problems. This collection of packages form the tidyverts, which facilitates a fluent and fluid workflow for analyzing time series.

Yihui Xie | pagedown Creating beautiful PDFs with R Markdown and CSS | RStudio (2019)
The traditional way to beautiful PDFs is often through LaTeX or Word, but have you ever thought of printing a web page to PDF? Web technologies (HTML/CSS/JavaScript) are becoming more and more amazing. It is entirely possible to create high-quality PDFs through Google Chrome or Chromium now. Web pages are usually single-page documents, but they can be paginated thanks to the JavaScript library Paged.js, so that you can have elements like headers, footers, and page margins for the printing purpose. In this talk, we introduce a new R package, pagedown (https://github.com/rstudio/pagedown) , to create PDF documents based on R Markdown and Paged.js. Applications of pagedown includes, but not limited to, books, articles, posters, resumes, letters, and business cards. With the power of CSS and JavaScript, you can typeset your documents with amazing elegance (e.g., a single line of CSS, “tr:nth-child(even) { background: #eee; }”, will give you a striped table, and “border-radius: 50%;” gives you a circular element) and power (e.g., HTML Widgets).

Claus Wilke | Visualizing uncertainty with hypothetical outcomes plots | RStudio (2019)
Uncertainty is a key component of statistical inference. However, uncertainty is not easy to convey effectively in data visualizations. For example, viewers have a tendency to interpret visualizations of the most likely outcome as the only possible one. Viewers may also misjudge the likelihood of different possible outcomes or the extent to which moderately rare outcomes may deviate from the expectation. One way in which we can help the viewer grasp the amount of uncertainty present in a dataset is by showing a variety of different possible modeling outcomes at once. For example, in a linear regression, we could plot a number of different regression lines with slopes and intercepts drawn from the range of likely values, as determined by the variation in the data. Such visualizations are called Hypothetical Outcomes Plots (HOPs). HOPs can be made in static form, showing the various hypothetical outcomes all at once, or preferably in an animated form, where the display cycles between the different hypothetical outcomes. With recent progress in ggplot2-based animation, via gganimate, as well as packages such as tidybayes that make it easy to generate hypothetical outcomes, we can easily produce animated HOPs in a few lines of R code. This presentation will cover the key concepts, packages, and techniques to generate such visualizations.

Sigrid Keydana | Why TensorFlow eager execution matters | RStudio (2019)
In current deep learning with Keras and TensorFlow, when you’ve mastered the basics and are ready to dive into more involved applications (such as generative networks, sequence-to-sequence or attention mechanisms), you may find that surprisingly, the learning curve doesn’t get much flatter. This is largely due to restrictions imposed by TensorFlow’s traditional static graph paradigm. With TensorFlow Eager Execution, available since summer and announced to be the default mode in the upcoming major release, model architectures become more flexible, readable, composable, and last not least, debuggable. In this session, we’ll see how with Eager, we can code sophisticated architectures like Generative Adversarial Networks (GANs) and Variational Autoencoders (VAEs) in a straightforward way.
