Hi, I need some help with the annotation package: To get the gene name for a given probe I perform something like this: > zebrafishGENENAME$"Dr.19073.2.S1_a_at" [1] "annexin A11a" My question is: How can I do it the other way around, i.e. get all probes with gene names containing "annexin"? Any hint will be highly appreciated. Cheers, Georg
