Running R with Singularity on Cypress

The ​ Rocker Project is a website established to provide docker containers in the form of docker files for the R environment.

In order to use any of those docker files on Cypress, we'll need to construct a container file - usually with .sif file extension - suitable for use with Singularity on Cypress. For reference in the following see Singularity.

Here's the sequence of commands to create and simply test a container file for the latest available R version - as provided the above website.

Start the interactive session

First, start an interactive session.

For Workshop : If your account is in the group workshop, please use the following.

[tulaneID@cypress1 ~]$idev --partition=workshop7 -c 2 # request 2 cores in the partition workshop7

Construct and check the container image file

Then proceed as follows to construct the .sif container image file and check the R version.

[tulaneID@cypress01-060 ~]$module load singularity/3.9.0 # load the singularity module
[tulaneID@cypress01-060 ~]$singularity pull docker://rocker/r-base:latest # takes a few minutes to construct file r-base_latest.sif
...
[tulaneID@cypress01-060 ~]$singularity exec r-base_latest.sif R --version # check the version of R
R version 4.5.2 (2025-10-31) -- "[Not] Part in a Rumble"
