To take our R workshops you need to install both R and RStudio. R is software that interprets text files written in the R programming language, and RStudio is a development environment/graphical user interface that makes programming in R easier. This guide shows you how to install R and RStudio, step-by-step. It has been adapted from video instructions on how to download R on R for the Rest of Us. If you prefer a platform-specific video tutorial on how to install R and R Studio, click here to see the installation on Windows, Mac, and Linux recorded in 2021 by Danielle Navarro.
