I believe that it depends on the operating system.
I think this is in the FAQ and search the R email list archive

I'm currently using a 2 GB Windows setup, but might have the option to run R on a server remotely.  Windows R seems basically limited to 2 GB memory if I'm right; is there the possibility to go much beyond that with server-based R?  In other words, am I limited by R or by my hardware, and how much might R be able to handle if I get the hardware necessary?

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
