About R¶

R is a free programming language and software environment for statistical computing and graphics. One of its appeals is the very large library of user-created packages that is available along with the ease of installing and using them. RStudio, a separate program that provides an interactive development environment (IDE) for R is also available and that can be run from Open OnDemand. We also install a couple of collections of libraries and make those available as loadable modules for your convenience. See below for details.

Using R¶

To make R available in your session, you can use

$ module load R

to get the default version. To see all available versions, use

$ module spider R

and all available R modules will be returned to you. You may load a specific version by including the version number on the module load command. For example, to load the R module for version 4.1.0, you would enter the following command:

$ module load R/4.1.0

We also provide several modules that include supplemental sets of R packages (also called libraries, which we will use interchangeably) preinstalled. Those are installed by the ARC software group and updated periodically. These include Rtidyverse, which includes the tidyverse collection of packages; Rgeospatial, which includes many packages useful for geospatial analyses; and Rmpi, which includes packages necessary for R to work with MPI.

Rtidyverse¶

The tidyverse is very popular collection of R packages designed for data science. With the dependencies it requires be installed, tidyverse adds up to several hundred R libraries. For convenience, we install the tidyverse packages and make those available via an Rtidyverse module on most systems, where the version is that of the underlying R used; so Rtidyverse/4.0.3 is R 4.0.3 with the collection of tidyverse libraries preinstalled.

Rgeospatial¶

This is all about Rgeospatial.

Rmpi¶

This is all about Rmpi.
