R Installation Notes

A discussion of the R configuration for cheaha is currently underway. The notes gathered on this issue and refined below will then be added to the appropriate local documentation for R.

Current Config

The R RPM's for R and libRmath have been installed on the head node and all compute nodes. A gnu version of R 2.3.1 and 2.5.0 is installed in /share/apps/R/R-2.3.1/gnu and /share/apps/R/R-2.5.0/gnu. For both of those, Rmpi_0.5-3 and snow_0.2-3 has been installed.

This essentially means there are 3 instances of R currently installed on cheaha:

• The RHEL4-supplied RPM version in the system path is R-2.3.0
• The R source versions in /share/apps/ are:
  • R 2.3.1
  • R 2.5.0
