Setting Up R Preferences with .Rprofile

For your convenience, ITaP provides a sample ~/.Rprofile example file that can be downloaded to your cluster account and renamed into ~/.Rprofile (or appended to one). Follow these steps to download our recommended ~/.Rprofile example and copy it into place:

$ curl -#LO https://www.rcac.purdue.edu/files/knowledge/run/examples/apps/r/Rprofile_example
$ mv -ib Rprofile_example ~/.Rprofile

The above installation step needs to be done only once on Hammer. Now load the R module and run R:

$ module load r/4.0.0
$ R
> .libPaths()
[1] "/home/myusername/R/hammer/4.0.0"                           
[2] "/apps/spack/hammer/apps/r/4.0.0-gcc-6.3.0-righufz/rlib/R/library"

.libPaths() should output something similar to above if it is set up correctly.

You are now ready to install R packages into the directory /home/myusername/R/hammer/4.0.0.
