Before coming to the lab, install R and RStudio on your computer. There are computers in the lab with R and RStudio installed, so if you are planning to use the lab computers for the semester, then you do not need to install.
You can find links for downloading R and other information about R on the R website https://www.r-project.org. You can download R from one of several CRAN mirrors. The simplest option is the cloud (https://cloud.r-project.org/), which will automatically redirect you to a local server.
Download and install the desktop version of RStudio from https://rstudio.com/products/rstudio/.
