Problems with expresso
Hello,
I want to use expresso for preprocessing the hgu133a-spikein data from
affycompII. But there is an error:
> library(affy)
> path <- "z:/Microarray/hgu133a-spikein/rawdata"
> celFile <- list.celfiles(path=path,full.names=TRUE);
> affyBatch <- ReadAffy(filenames=celFile[1:6]);
> eset1 <-
expresso(affyBatch,bgcorrect.method="rma"...
