R (statistical computing)

Last updated on

A popular, full featured, statistical computing package

Introduction

The "R" Tool is an open-source, popular, and fully-featured statistical application and programming platform. We have multiple R versions installed on HPC.

Running R on RCC Systems

To enter an interactive R session on HPC or Spear, simply "R" command.  The default version that loads is Version 3.4.0.  If you wish to run an older version, you must load the appropriate module before running "R"; e.g.:

# loads version 3.2.5
module load R/3.2.5

# loads version 3.2.0
module load R/3.2.0

# loads version 4.0.0
module load R/4.0.0

Type 'q()' to quit R.

To submit R jobs to SLURM, refer to the following example submission script:

#!/bin/bash

#SBATCH -n 1
#SBATCH -J "MyRJob"
#SBATCH -p backfill
#SBATCH -t 1:00:00
#SBATCH --mail-type=ALL

module load R/3.2.5

R CMD BATCH yourRscript

The yourRscript is a text file where you have saved R commands to run.

For more information about R, refer to the online documentation

Installing R Packages in Your Home Directory

Though RCC hosts many packages on our systems (see list below), there may be times when you need a specific package we do not currently have. In this case, you can install this package locally in your home directory using the following instructions (no need to open a ticket!):

  1. Type: module load R
  2. Type: R
  3. Type: install.packages("PACKAGE_NAME_HERE")
  4. This will present you with the following information: Installing package into ?/opt/hpc/R/R-3.5.2/shar/R/library? (as ?lib? is unspecified)
  5. You will then see a warning:  Warning in install.packages("abc") : 'lib = "/opt/hpc/R/R-3.5.2/share/R/library"' is not writable. This is normal.
  6. You will then be asked:  Would you like to use a personal library instead? (yes/No/cancel). Type yes
  7. You will then be asked:  Would you like to create a personal library ?~/R/x86_64-redhat-linux-gnu-library/3.5? to install packages into? (yes/No/cancel). Again, type yes
  8. You will then be shown: --- Please select a CRAN mirror for use in this session ---
  9. This will bring up a list of CRAN mirrors you can use to download and install your library.
