Hello, I have googled my self half to death, I cannot understand this:
select(hta20transcriptcluster.db, keys=featureNames(vv), columns=c("SYMBOL","GENENAME"), keytype="Ensemble")
Error in testForValidKeytype(x, keytype) :
Invalid keytype: Ensemble. Please use the keytypes method to see a listing of valid arguments.
My probes look like this:
 "TC0100013150.hg.1" "TC0100013155.hg.1" "TC0100013156.hg.1" "TC0100013158.hg.1"
I really cannot figure out that the "keytype" for these probes are.. Data are obtained by HTA-2.0. I know its not "Ensemble", but I have tried everything I can think of, and I just dont get it. Google has not helped and I have read every single thread on the internet the resembles this problem.
Nevermind! After hours of trial and error, i figured it was from the Clariom D Human Microarray CDF file to package. clariomdhumantranscriptcluster.db is the way to go.
