Hi Guys,

I know this question has been asked many times before, but all the
"solutions" I try seem to fail.

I have a Dell Optiplex, 2 X 3.4Ghz Dual Core Processor with 4Gb of RAM
running windows XP Professional.

I am trying to read in a measly 16 HG-U133 Plus2.0 arrays using the
following script.

 

celnames <- choose.files(caption="Choose CEL file(s)")

celnames <- sort(celnames)

Data <- ReadAffy(filenames=celnames)

 

However, I get the "Cannot allocate vector of size" error.

I have tried adding the --max-mem-size=2Gb tag onto my shortcut.

Using memory.limit(size=4000) 

The thing is I've used the same PC to analyse 27 arrays before, so I'm
not sure what's chanaged. I'm shut down as many applications running on
my system as possible.

Is there an idiot's guide on how to get R to use more memory anywhere?

 

Thanks in advance

Tony
