Hi Skov -- this is a Bioconductor question, so ask on the Bioconductor
mailing list.


There are alternatives to affy::ReadAffy that might work on your current
machine, including affy::justRMA, the aroma.affymetrix package, and the
xps package (which requires a system dependency that some find difficult
to install).

Others on the bioc list might have more guidance on memory requirements
on 64 bit linux systems, which is what you'll want for large data analysis.
