R help - Jan 2012 - Restricting R session

Hello,

Is it possible to use R on public server where each user has its own
restricted R session?
In particular, how to prohibit some set of functions, for example,
from "base" package?
How to limit session operating memory and CPU time? What additional
security considerations must be taken care of?

Kind regards,
Antonio Rodriges

This entirely depends on the definition of "restricted", otherwise the
answer is "yes".

You can't: R is free software. Well, of course you could build your own 
version of R that did not ship those functions. Anyway, typical 
restrictions are handled by settig permissions on the file system and/or 
arrange quotas for space / memory / CPU resources.

Ask he manual of your operating system.
