[BioC] U133plus2.0 memory problem

[kfbargad at lg.ehu.es]

Sorry this has come up many times and I have looked for an answer in 
the mail archives, but I couldn´t find anything regarding amount of 
memory for many U133plus arrays.

I have 60 U133plus2.0 arrays and I wanted to do some NUSE plots, but I 
can´t even read in the arrays using ReadAffy() and I know fitPLM() is 
more demanding.

I am running R 2.0.1 and affy 1.5 on a Pentium 4 with Windows 2000 OS, 
1G RAM. I tried increasing the memory by

memory.limit(700000) 

but still get the error "cannot allocate vector of size 635107

any suggestions??

thanks,

David
