What kind of "access" do you need? You can specify a formula (or even a
model matrix, if you prefer), and you get all coefficients ande
Of course, you can call glm.fit or statmod::glmnb.fit directly. Then,
however, you should _not_ use the normalized counts but rather specify
the log size factors as offsets.

No, I used R 2.15. See the explanations on the Bioc web page on how R
and Bioc versions are tied together, and how devel packages are handled.
