# ARCHIVED: Install and load R packages on Big Red II at IU

R is a language and environment for statistical computing and graphics. R provides a wide variety of statistical (for example, linear and nonlinear modeling, classical statistical tests, time-series analysis, classification, and clustering) and graphical techniques, and is highly extensible. For more, see the R Project for Statistical Computing home page.

To use R on Big Red II, you first must add it to your user environment; for instructions, see ARCHIVED: Use R on Big Red II at IU.
