Dear list: I am wondering if there is an easy way or a function by which one can extract (list) any session of genes, either in common or not in common with other sesseion(s), in vennDiagram of limma? I assumed that vennDiagram should be able to allow to do that. But I did not find anything like that after reading the on-line instructions. Many thanks if you could help me out!
