[BioC] Multi-factor designs with specific comparisons

[Tom [guest]]

Dear list,

Using DESeq GLMs, how can I make comparisons with more than 2 levels e.g. Group A, B, C and D? I would like to test for pairwise for differences between A and B (without C and D), between A
and C (without B and D) etc.

Thank you very much.
