I am trying to analyze microarray data with R and am stuck at annotation step. I was wondering if anyone could help.
Here's the code i have so far
OligoEset<-rma(OligoRaw) # 35556 features, 24 samples
ID <- getMainProbes(OligoEset)
annot <- select(mogene10sttranscriptcluster.db, featureNames(ID),
c("SYMBOL","GENENAME","ENTREZID")) # 36631
I am stuck at trying to merge the "annot" with "OligoEset". I would like to have annotated and normalized data set in a dataframe/.txt/.xls files to analyze.
I'd very much appreciate any help.
