R help - Aug 2004 - A question about memory size

Hi....

I have a question about how to increase my memory size, could someone answer it
for me??

I am using Bioconductor in R to calculate gene expression values with mas5,
dchip, and mas4. I have only 18 samples, all from Affymetrix U133A Plus 2
arrays, which has ~54,000 genes. My machine equipments are: CPU P4 3.0GHz, and
1GM RAM. Somehow when I was running mas5 in R, it always showed the error
message: "Cannot allocate vector of size 211702 Kb." I believed that
it would be a memory setting problem, so I tried to use the command:
memory.size(TRUE) or memory.limit(size=NA) to increase the memory. But it still
didn't work!!
Can someone tell me what's going on and how can I run it?? I really
appreciate it. Thanks.
