Vista 64-bit whereas UNIX will make use of closer to the full amount of
RAM.
Is this correct? Is there a way to make the windows version of R use
more of the available RAM? Or is going for a UNIX OS the better
solution?
See the rw-FAQ for info on 64-bit builds of R under Windows.
Any advice would be very much appreciated!
