[Bioc-devel] Alternative Hypothesis Specification For edgeR

Hi Dario,

I guess so - it would be a fairly easy extension of glmLRT - but why? I 
can't think of many situations where a non-zero log-fold change is 
expected under the null hypothesis. Mixture experiments, or correcting 
for gene dosage due to copy number variants, perhaps.

Cheers,

Aaron
