R Programming Language

R is a statistical programming language that is especially powerful for data exploration, visualization, and statistical analysis. To interact with R (initially), we will primarily be using RStudio, an interactive development environment (IDE).

We will mostly be using a browser based version of RStudio on a remote server but you can also install a local version of the RStudio IDE.
