UO Psych R Bootcamp 2020


I organized and taught a 3-day introductory R Bootcamp for my fellow ducks in the Department of Psychology at the University of Oregon in September 2020. This bootcamp gives a gentle introduction to R and RStudio, transforming and visualizing data with the tidyverse, and the basics of R Markdown. It assumes no prior experience with R or any other programming language and is designed to get learners up and running with the most widely useful tools for reproducible data analysis in R while emphasizing best practices for writing code and organizing project-oriented workflows.

Column-wise operations with dplyr: Old and New


While preparing to become an RStudio Certified Instructor, I put together a lesson on column-wise operations using the dplyr package – in other words, how to apply data transformations to multiple columns of data simultaneously. This was a fun opportunity to not only learn about this topic in much greater depth but also to implement modern teaching methods I had recently learned, including concept maps , learner personas , and formative assessment , among others. You can find the source code and accompanying materials for this lesson on Github .

Introduction to Git and Github


I taught an introductory workshop for first-year psychology PhD and Master’s students on basics of using Git and Github for version control in February 2020. I also taught a more advanced version of this workshop for University of Oregon’s Data Science Club in 2019, including a discussion of merge conflicts, branching, pull requests, and best practices for collaborative Github projects. I regularly use Github to more easily track and share my work, and I have enjoyed the opportunity to help my fellow grad students get started with learning the “why” and “how” of using version control.
