A few Ceres-specific notes:
1. **RStudio terminal** (bash command shell): since RStudio Server is running in a container with a Debian base image, you won’t be able to access software environment modules (e.g., that you would normally see when logging into Ceres and issuing the `module list` command), as those are installed on the (CentOS) host.
2. **Data access:** your home directory is mounted inside the RStudio Server container, and the VRSC has configured Singularity to mount the /project directory. $TMPDIR (which on a compute node is per-job local scratch on the compute node’s direct attached storage that gets deleted at the end of SLURM job) is mounted inside the container at /tmp.
3. **Software installation:** The provided SLURM job script creates a ~/.Renviron file in your home directory that allows RStudio to install additional R packages into your home directory (the container image is immutable). Installing a lot of R libraries may contribute to the default 5G soft limit quota on your home directory being surpassed. To overcome this issue you can move R directory from your home directory to your project directory and create a symbolic link to the new location. In RStudio click on "Terminal" and enter the following commands substituting your values:
