Colin Rundel | parsermd - parsing R Markdown for fun and profit | RStudio

parsermd is a new R package for parsing and programmatically interacting with R Markdown (Rmd) documents. This package implements a formal grammar for Rmd documents in C++ using Boost’s Spirit X3 library and provides additional user facing functions for the resulting abstract syntax tree. In this talk we will provide background on the structure and grammar of Rmd documents as well as discuss the ways in which the parsing of these documents enables a variety of automatable tasks. Specifically, we will focus on demonstrating how these tools can be used to provide automated feedback on student submissions in a statisical programming course.

About Colin: Colin is a lecturer in Statistics and Data Science at the University of Edinburgh. He has been teaching statistics and data science courses, with a focus on computing and spatial modeling, for the last 8 years

Colin Rundel | livecode: broadcast your live coding sessions from and to RStudio | RStudio (2020)

In this talk we will demonstrate livecode, a new R package for broadcasting code for live code demonstrations. This package implements a simple webserver (using httpuv) to dynamically publishes the content of a code file (i.e. .R or .Rmd) as you edit it live. This enables your students to have near realtime access to your code as you write it. The broadcast file can be viewed with any webbrowser but the package is specifically designed to be used within RStudio leveraging its builtin viewer. This gives students have direct access to the shared code within the IDE, allowing direct copying into their own source files and/or the console and thereby improving their ability to interact and experiment with your code.
