Hate to say that, but it looks like Stata is way above R, considering exact logistic regression. To use elrm() I have to aggregate my data,which is really time consuming when I look for the way out through many variables. But the worst thing is that I am not not sure if I can trust to p-values in output.
I would be happy,however, if someone could contradict me on this issue.
