R help - Jul 2011 - Simulating from the Null

Hello all,
I am doing  glm with a negative binomial link.
I have two treatments and 3 replicates in each treatment. My question is
this, how can I simulate data for the the columns  from the null and
distribution.

Thanks,
Jim.

Simulate from the null:
fit the null model and use the simulate method:

nullmodel <- glm.nb(response~1,data=yourdata)
simulate(nullmodel)

Simulate from the fitted distribution: as above, but
fit the full model.
