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?

Hi,

R under Windows can handle up to 2GB, and under certain conditions up to 
3GB. Note that no 64-bit version for Windows is available yet.

Anyway, under 64-bit Linux their are almost no limits other than 
hardware restrictions.

Best wishes,
Uwe
