[BioC] affy & problems with memory

Hi Nick,

I'm currently working on that chip type myself on a system with 512MB RAM
and had to increase the memory assigned to R too. However
"--max-mem-size=1024Mb" seems to be ok in my case. Besides the problem of
how much memory is necessary for the hgu133plus2 maybe somebody out there
could answer me this two related questions:
* I'm running R under WinXp AND under Linux on the same machine. However
there has never been any memory problem in linux. So is the memory
allocation or the  assignment of the max. memory size that can be used by R
different in the two systems?
* With my 512MB RAM system the old maximum memory value under WinXP was
512MB. Is this just a coincidence or does this maximum value rise to 1024MB
if I upgrade my system to 1024MB RAM?
