[BioC] Problems with justGCRMA: Error in bg.adjust.fullmodel

[Jordi Altirriba Gutiérrez]

Dear users,
I’m trying to obtain the GCRMA expression values of 26 Affymetrix 
microarrays (HGU133plus2). Due to a limitation of RAM (2Gb), I can’t use 
GCRMA directly:

Data<-ReadAffy()
esetGCRMA<-GCRMA(Data)

So I’m trying to do it with justGCRMA, but I’m obtaining this error:

>esetGCRMA<-justGCRMA(filenames=list.celfiles(),type="fullmodel",optimize.by="memory",fast=TRUE)
Computing affinities..Done.
Adjusting for optical effect...........................Done.
Adjusting for non-specific binding.Error in bg.adjust.fullmodel(pms[, i], 
mm, pm.affinities, mm.affinities,  :
        unused argument(s) (Q ...)

I’ve also tried with 
just.gcrma(filenames=list.celfiles),type="fullmodel",optimize.by="memory",fast=TRUE)

But I’m obtaining the same error.

The data of my computer and R:
PC: Intel centrino M 2GHz
OS: Windows XP pro

R version 2.1.0, 2005-06-02, i386-pc-mingw32

attached base packages:
[1] "tools"     "methods"   "stats"     "graphics"  "grDevices" "utils"  
"datasets"  "base"

other attached packages:
        vsn       plier       gcrma matchprobes        affy  reposTools
    "1.6.3"     "1.0.0"     "1.1.3"    "1.0.22"     "1.6.7"    "1.5.19"
    Biobase
   "1.5.12"

Any help will be very much appreciated.

Thanks for your time
