R help - Oct 2012 - How to limit memory on a server

Hello,
In our structure, users connect to a server (64GB of memory) where they launch
R. How can I limit the amount of RAM that could use a user.
The function memory.limit(size=...) can limit the amount of memory but I would
like users can't change this option in R. Is it possible?
Thank you.

Generally speaking, that's something that the operating system needs to 
enforce.   If you don't know how to do it with your OS, you might get 
some advice here by saying which one it is, but you may have to ask a 
sysadmin at your site.

And your OS is?  See the footer and the 'at a minimum' information the 
posting guide asks for.

I think you are confusing 'memory' and 'RAM': the two concepts
are distinct.

But R is not a special case, and you do it the same way as you do this 
for any other process, by your OS facilities.
