Hi list How do i find common genes between different datasets? peevi [[alternative HTML version deleted]]

You need to define your terms more clearly. If the datasets have vectors of tokens identifying genes, R's intersect() function will give you a start. If the datasets are annotated with diverse vocabularies (probe IDs in one, entrez IDs in another) you will have to harmonize them somehow. GSEABase package provides some facilities for translating token sets. Departures from 1-1 correspondence are common and policies for simplifying maps need to be devised.
