Hello,
I am getting an error for an object ".qcEnv" not found when trying
to plot(qc).  
This is the code:
library(simpleaffy)
library(mouse4302cdf)
abatch <- ReadAffy(celfile.path=celpath, widget=F)
abatch.mas5 <- call.exprs(abatch,"mas5")
qc <- qc(abatch,abatch.mas5)
plot(qc)
Error in get("alpha", envir = .qcEnv) : object ".qcEnv" not found

R version 2.2.0, 2005-10-06, i386-pc-mingw32 
other attached packages:
mouse4302cdf simpleaffy genefilter survival affy Biobase 
"1.10.0" "2.4.2" "1.8.0" "2.20" "1.8.1" "1.8.0"

Can someone tell me how to set the ".qcEnv"?
