I am trying to analyze microarray data of 42 human arrays. I typed in the following instructions: library(affy) Data <-ReadAffy() eset <- expresso(Data, normalize.method="invariantset", bg.correct=FALSE, pmcorrect.method="pmonly",summary.method="liwong") And I get some sort of memory error that crashes the R program. Specifically it states: R(1763) malloc: *** vm_allocate(size=346857472) failed (error code=3) R(1763) malloc: *** error: can't allocate region R(1763) malloc: *** set a breakpoint in szone_error to debug R(1763) malloc: *** vm_allocate(size=346857472) failed (error code=3) R(1763) malloc: *** error: can't allocate region R(1763) malloc: *** set a breakpoint in szone_error to debug Error: cannot allocate vector of size 338724 Kb R(1763) malloc: *** vm_allocate(size=8421376) failed (error code=3) R(1763) malloc: *** error: can't allocate region R(1763) malloc: *** set a breakpoint in szone_error to debug Any ideas? My computer has 2gb of RAM and 100 gb free. I would think that analyzing 42 microarrays would not be too difficult.
