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
