[R] 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. [[alternative HTML version deleted]]

Re: [R] Simulating from the null distribution of a 2 x 3 table

Thanks for all your help thus far. My final question is this, if I want to simulate all the 2 x 3 tables (with column totals and row totals fixed), how do I do this using r2dtable(), and find the one that gives me the smallest fisher's exact test. Will r2table() generate unique tables everytime to
