Re: [R] How to limit memory on a server
I think R keeps all the data in RAM ? The function memory.limit() refers to the RAM size ? I will try to configure the OS. Thanks.

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.
