Using R 4.5.1 on Cheaha via RStudio Server

Default R Version

The latest version of R installed on Cheaha is R 4.4.1.

R 4.5.1 Availability

If you need R 4.5.1, you can use a container image created by Fortune of UAB RC’s team. Follow the steps below.

Steps

1. Launch an HPC Desktop job.

2. Pull the container image:

    singularity pull rstudio-r451.sif docker://code.rc.uab.edu:4567/rc-data-science/community-containers/rstudio451/rstudio451:latest
   

3. Create required directories:

    mkdir -p $HOME/rstudio-server $HOME/rstudio-logs $HOME/rstudio-run $HOME/rstudio-etc
   

Note: The rstudio-etc directory is required because RStudio Server attempts to write configuration files to /etc/rstudio, which is read-only inside the container unless explicitly overridden.

1. Start the container:

    singularity run --writable-tmpfs -B $HOME/rstudio-etc:/etc/rstudio -B $HOME/rstudio-server:/var/lib/rstudio-server -B $HOME/rstudio-logs:/var/log/rstudio-server -B $HOME/rstudio-run:/var/run/rstudio-server rstudio-r451.sif
   

2. Open a web browser within the HPC session and navigate to:

    http://localhost:8787
   

This will launch RStudio Server. From there, install packages as usual and run your R scripts.
