Good Morning I am trying to analyze a single channel agilent dataset. But I cannot seem to find how to retrieve probe info from pData object, i.e. the matrix I end up with contains no probe IDs. Please advise as I am really stuck at this point. gset <- getGEO("GSE48113", GSEMatrix =TRUE) if (length(gset) > 1) idx <- grep("GPL15331", attr(gset, "names")) else idx <- 1 gset <- gset[[idx]] ex <- exprs(gset) > head (ex) [1:2,1:5] GSM1168586 GSM1168587 GSM1168588 GSM1168589 GSM1168590 1 NA 17.60373 18.32132 18.22676 17.5361 2 NA NA NA NA NA Any help is much appreciated Thanks a lot Alyaa -- Alyaa Mahmoud "Love all, trust a few, do wrong to none"- Shakespeare [[alternative HTML version deleted]]
