Hi, I was trying to compare differential expression data from multiple studies ( 4 dataset downloaded from NCBI GEO). The expression dataset are from Affy, as well as cDNA (dual channel) platforms. Before I conduct analysis, I have to map the gene IDs so that the different genes are comparable.
Which packages, and what commands do I need for this? thanks, Pankaj ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
