[R] how to get Rscript, and is there any reason not to?

[Tom Roche]

As described in the thread beginning @

https://stat.ethz.ch/pipermail/r-help/2012-September/322985.html

I work (as a user, without root) on a cluster that has several servers
on which R is installed but not Rscript. I'd like to know

1 What should I tell my admin to do in order to make both Rscript and
  R available? (FWIW I believe the boxes are running CentOS, though
  possibly RHEL 5 or 6.)

2 Is there any reason to install R without Rscript? Alternatively,
  when I ask my admin to install Rscript, is there any objection
  I should anticipate?
