Problems with expresso
...sso 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",normalize.method="quantiles",summary.method="medianpolish")
background correction: rma
normalization: quantiles
PM/MM correction :
expression values: medianpolish
background correcting...done.
normalizing...done.

filtering probesets with Bioconductor?
Hi,
I am relatively new to R and Bioconductor and am trying to filter the
topTable that I generated of differentially expressed genes from my
normlized eset file comprised of ~ 40 HG-133A Affy microarrays . I would
like to see if particular probesets are represented in this list.
Alternatively I would like to
generate a topTable of differentially expressed genes using only specified
probesets
