=== R ===

The "R" statistical/programming package is installed on the clusters.  The greatest number of add-on packages are installed in the 4.0.2 version.  Also included are older saved versions, newer 4.1.0 and R 4.2.2 and slightly modified Microsoft R Open 4.0.2 [[https://web.archive.org/web/20200808203121/https://analyttica.com/microsoft-r-or-open-source-r-which-suits-you-the-best/]].

<code>
module load gcc/9.3.1 mkl/19.0.5 R/4.2.2
</code>
"gcc" module may be omitted unless you are adding R packages (see below).  Substitute R/4.1.0 or MR/4.0.2 as desired for those versions.  You can also add rstudio if you want the gui.  This is best run through a portal (via interactive-apps Desktop or Rstudio GUI).
<code>
module load gcc/9.3.1 mkl/19.0.5 R/4.2.2 rstudio
</code>

If you need a new R package, you can ask hpc-support to add it to the central installation, or you can add your own packages as demonstrated below for the package "broman".  R is not as prone to conflicts as Python, so most packages can be added to the central installation without issues.  Another way to create a custom installation is using [[python|conda]], which would be better if you see conflicts with standard ''R''. It will, however, install many thousands of files in your home.

For this simple installation, before starting, create files ~/.Rprofile and ~/.Renviron as shown, plus  the R library directories (changing full version 4.2.2 to 4.2 in this example) and any of the other R environment variables you may want to set [[https://rstats.wtf/r-startup.html|rstats.wtf]].   

<code>
pinnacle-l4:feynman:$ cat .Rprofile
options(repos = c(CRAN = "https://mirrors.nics.utk.edu/cran"))
pinnacle-l4:feynman:$ cat .Renviron
R_LIBS_USER=~/R/%p/%v
pinnacle-l4:feynman:$ cd;mkdir -p R
pinnacle-l4:feynman:$ mkdir -p R/x86_64-pc-linux-gnu
pinnacle-l4:feynman:$ mkdir -p R/x86_64-pc-linux-gnu/4.2
</code>

With those files in place you can install any R package yourself. Some redundant text output below has been omitted. 

<code>
pinnacle-l4:feynman:$ module load gcc/9.3.1 mkl/19.0.5 R/4.2.2
pinnacle-l4:feynman:$ R
