Was this by any chance a Linux on x86? If so, I think there's roughly a 2.5-3GB limit for a single process imposed by the architecture.

Hmm, I went over to a unix box that should have had plenty of RAM and swap
space and running the same prune.tree process ended up causing R to be
"Killed" (e.g. It quit out).  Thoughts?

I have 2GB installed on my windows XP box running R 1.9.0, and after
performing a prune.tree(intree,newdata), I get an out of memory error within
R, but it says the maximum allowed is 1024gb (1/2 of what I have!)  Can R
not use more than 1GB on an XP box?  I noticed I had ~600mb left over after
R conked out, so clearly I had more memory...  What about virtual memory?

See the FAQ. You can increase the limit, but not past 2GB (no matter how much RAM or virtual memory you've got), and maybe not all the way there.
