[R] exact logistic regression

[Den]

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.
With best regards
Denis
