See below for resources associated with the coding workshops from SIPPS 2023. For materials from other years and/or workshop series, follow this link.
Week 1: Setting up your R environment
Before the workshop:
Before the workshop, please install R and RStudio on your computer. We have compiled this assortment of videos (not made by SIPPS instructors) that go over how to install these programs in Mac & PC, as well as introduce you to the RStudio environment.
Installation:
- Installing R & RStudio (Mac)
- Installing R & RStudio (PC)
- Note: Make sure to install the latest versions of R & RStudio, even if they don’t match exactly what you see in the videos.
Intro to RStudio:
- Introduction to RStudio (original video pulled from the Columbia Psychology Scientific Computing workshop series)
- Tour of the RStudio Interface
- Note: You don’t necessarily need to watch both of these videos, just enough to familiarize yourself with the basics of what RStudio looks like and how to use it.
During the workshop:
Create create a folder named 01_setup on your computer and download these files within that folder:
After the workshop:
Review these slides from the workshop. (We covered through slide 38, but feel free to review beyond that.)
Note that for this workshop, we only expect that you: (1) have successfully downloaded R & RStudio, (2) have some basic understanding of the different panels/panes of RStudio, how to open files, etc., and (3) know how to install and load packages (including tidyverse, car, psych, and lme4). We will get into the details of how to start actually writing R code next week.

Download this file for the synchronous workshop session & place it in the same 02_intro-programming folder.
After the workshop:
Review the answer key for challenge completed during the workshop. (We strongly recommend trying to work out answers yourself and/or talk to the instructor before consulting this answer key.)
Week 3: Data cleaning
Before the workshop:

Note: In the pre-workshop video, the name of the project folder and R project file used start with
04instead of05. Either numbering scheme is okay, just make sure your R project file has the same name as the folder you create to store these materials.
During the workshop:
