Hi,
I am working with R on 2xG5 1.8Ghz from Apple under 10.3.8 The G5 chip is 64 bits but does R run in 64 bit or 32 under OS X? How can know? I think it run in 32 bits... but not sure...
Under the current OS X it runs 32bit. You can tell by looking at .Machine$sizeof.pointer which is 4.
The next version of OS X is advertised as having full 64bit support so this limitation will go away then.
