Several versions of R version are installed and can be accessed by all users.

Setting up the path and environment:

All required environment variables can be set by loading the R module, to do this issue:

$ module add R

Launching on the front end

R can be launched by entering its name at the command prompt; i.e.:

$ R

Please note that this method should not be used apart from for quick tests. Exit the R console by typing.


Running through an interactive shell

The following will launch R interactively via the batch queues.

$ qrsh -cwd -V -l h_rt= R 

The <startup_flag> can be –save , –no-save or –vanilla . I have used –vanilla but information on the meaning of these flags can is here. In the above command, is the length of real-time the shell will exist for. e.g. to run R for 6 hours:

$ qrsh -cwd -V -l h_rt=6:00:00 R --vanilla

This will run R from within the terminal from which it was launched.

Batch Execution

To run R in batch-mode you must first generate a list of commands for R to process in a file, e.g. r.in. You needed to make sure that this file is executable. You can do this by running the command chmod u+x .sh. You can check this by running the command ls -la command and the information for that line will contain an x for execute like this -rwxr–r–.

A script must then be created that will request resources from the queuing system and launch the R executable; script runR.sh :

# Run in current working directory and use current environment
#$ -cwd -V
# Set a 6 hour limit
#$ -l h_rt=6:00:00
#Request more memory, the default is 1Gb
#$ -l h_vmem=1536M
# Load R module
module add R
# run R using command file
# CMD BATCH flag should be given to suppress graphics
R CMD BATCH r.in r.out

This can be submitted to the queuing system using:

$ qsub runR.sh

The files for a simple R test example are available to download in this tar file, R.tar.

Installing R packages

Given the large number of R packages available and pace of development, it is preferable that users install the packages they need as opposed to using a centrally provided set of packages.

R 2.15.0 and later

To install package foo , start an R session by entering its name at the command prompt; i.e.:

$ R

and then from within R, install the package:


This will install the package and any dependencies that are required. The package should then be accessible from subsequent R interactive sessions and batch jobs.
