Part 1 What is R

R (R Core Team, 2020) is an open-source language and environment that is primarily used for conducting statistical analyses and managing data. RStudio (RStudio Team, 2020) is an open-source graphical environment for running R, viewing output, and doing other things (like creating this document).

The R community is huge and people develop R packages that we can download (through R) and use for specific types of analyses. In later tutorials, we will use many packages, such as the ggplot2 package (Wickham et al., 2020) and the psych package (Revelle, 2020).
