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.
