Dear Bioconductor mailing list,
is ther a sensible way to deal with redundant probesets on Affymetrix chips
like the HG-U219?
For Example:
  Probe Set ID RefSeq Transcript ID  11715100_at NM_003534  11715101_s_at
NM_003534  11715102_x_at NM_003534
Should I get the median/mean of te expression intensities? Or select the
highest? And what would be the procedre in R to do it? I mean, how do I tell
R to return the median of expression values if there are more than 1
probesets for only 1 refseq ID?

I hope you can help me, Andreas
