[R] exact logistic regression

[Denis Kazakiewicz]

Dear Łukasz
Thank you very much for information
Dear R people could you please help please with following questions 
Sorry for my silly questions, because I am not a mathematician.
1. Is elrm() works similar as exact regression in SAS or Stata?  After
double check in Stata and R some results from my data vary greatly. 
2. How to obtain p-value from MCMClogit() from MCMCpack?

Thank you
Denis
