Subject: 64-bit R on OS X/G5?
In-Reply-To: <87D57BA0-BF7F-11D8-8D66-000393CE2F0C@math.chalmers.se>
R works on 64-bit platforms and has for quite a while, currently I know of
people using machines with 16Gb RAM on 64-bit platforms (Alpha, Sparc,
AMD64).
Do you have a full 64-bit compiler and runtime for MacOS X? If so `all'
you need to do is to run compile under it. One quote I picked up was
macos X has 64 bit support with gcc 3.3 and a g5
which if correct suggests this is possible.

There is of course a memory limit but it far exceeds 8GB. There is a
limit on the length of vectors still (2^31 - 1) and a few other similar
limits.
