To anyone with a lot more experience.
I have been trying to read through all the helps and vignettes for a
simple
way to get the probesets that went into producing significance of KEGG
term
after running hypergeometric test for KEGG. I have found
probeSetSummary
for GO terms and hyperGoutput (also for GO terms) but nothing
corresponding
for the KEGG. Was hoping someone had a simple methodology for
retrieval.
Thanks
Louisa

ProbeID
first, so they each take up a row, rather than being one long string that runs off the page. HTH, Jim Louisa A Rispoli/AS/EXP/UTIA wrote: > Jim- > > Thank you for the prompt reply.
