Using R

Contents

Location

R is contained in the pkgsrc Modules, for example:

$ module switch env env/2025Q1-gcc-openmpi
module: unloaded env/2025Q1-gcc-openmpi
Module for pkgsrc-devel 2025Q1 unloaded.
module: loaded env/2025Q1-gcc-openmpi
Module for pkgsrc-devel 2025Q1 loaded.
$ R --version
R version 4.4.2 (2024-10-31) -- "Pile of Leaves"

Installing R packages in $USW

R packages should be installed in $USW (“User-installed SoftWare”).

Steps:

  1. Create a directory in $USW, for example
    mkdir $USW/R-packages
  2. Tell R to use that directory. This can achieved in two ways:
    • in ~/.Rprofile
      .libPaths(paste(Sys.getenv("USW"), "R-packages", sep='/'))
    • in your shell profile (~/.profile or ~/.bash_profile or ~/.bash_login)
      export R_LIBS_USER=$USW/R-packages
