Rhea

On Rhea (linux server), older R versions exist for legacy pipelines and scripts. For example, see /opt/ni_tools/R/R-4.4.1/bin and packages in /opt/ni_tools/Rlib/4.4.1 (created 2025-08-11 with bump to debian 13/“trixie”, R 4.5.1 “Great Square Root”).

In a shell script, you can update the PATH to force older R. 

export PATH="/opt/ni_tools/R/R-4.4.1/bin:$PATH" # default to R 4.4.1

Or call explicitly. 

/opt/ni_tools/R/R-4.4.1/bin/Rscript -e '
       .libPaths("/opt/ni_tools/Rlib/4.4.1");
       print(version$version.string);
       installed.packages()["dplyr",c("Built","Version","LibPath")]
