I'm struggling my way through beginner's Bioconductor (and R in general) and have a specific problem I hope somebody can help with. I can load CEL files, do RMA processing on them and check QC etc, eventually I end up with a data frame with these data.
I have a few lists of about 200 candidate genes each that are of specific interest to us and I would like to run a script to print the expression data for just those genes to a tab-delim txt file.
Can anybody point me in the right direction to do this. I do have the Affymetrix Probe Set IDs for these, so can use either that or gene symbol.
Apologies if this is a very basic question, I'm very new to this.
Thanks in advance, Kerem.
