I'm trying to normalize the data from multiple studies performed using same platform.
ibrary(gcrma) library(limma) downloadedAffyFiles <- list.files(path = "GSE53454_RAW/", pattern = "CEL.gz$",full.names=TRUE) AffyData <- ReadAffy(filenames = downloadedAffyFiles) eset <- gcrma(AffyData)
Could someone help on how to access the contents of the expression set?
exprs(eset) gives the log-expression values.
How do we access the contents like cell type description? For Instance, while working with the series matrix files, pData(eset)[] works.But, I am not able to use the same commands here.
