[BioC] How to filter up- and down-regulated genes?

[Vitalina Komashko]

Dear Sean,
Thank you very much for your fast reply. Yes, I am using a t-test and I
supposed that I should do exactly that you advised. Problem is that I do not
know how I could implement it in R : to filter genes according the sign of their t-statistics and adjusted p-value.

Thank you very much.
