Using R-1.8.0 (d/l and compiled on 2003-10-01) on WinXP, I seem to be unable to determine the maximum memory allocated to R. The help still says to use memory.limit(size=NA), but this returns the value NA.
In addition, I have set --max-mem-size=2G but I run out of memory somewhere around 500Mb (which is why I am trying to find out how much memory is allocated). I don't have any other programs open, so I should certainly be able to address more memory than that.
Any ideas?
Yes. 2GB is a bit more than the possible theoretical maximal value for a single process on 32-bit Windows. Instead, try starting with, e.g., "--max-mem-size=1700M" and you'll get
> memory.limit() [1] 1782579200
