Dear Bioconductor Authors,

I fitted a generalized linear models using glmFit() in edgeR. I wanted to extract the estimated fisher information matrix (or the estimated inverse fisher information matrix) from the fitting. The function approx. expected.info() in edgeR seems to be the right function to use. However, I have two problems when using it: (1) It does not work with the GLM since it requires the pseudo.alt argument which is provided only in the one-way layout framework; (2) I have ~30,000 tags, and it takes more than an hour to run. Could you please let me know how to extract the estimated (inverse) fisher information matrix?

Thanks,
Tieming
