Hello, I'm trying to generate a p.value directly from the output of a fisher exact test odds ratio statistic without resorting to performing another test on the 2x2 table itself. The motivation for this stems from a need to modify the test statistic before calculating it's new p- value.
I've looked at the c source code for both fisher.test and phyper and they both seem to operate directly on the 2x2 table rather than the statistic. Can anybody think of a way to do this short of recovering the cell probabilities from the odds ratio (as described here: http://en.wikipedia.org/wiki/Odds_ratio#Recovering_the_cell_probabilities_from_the_odds_ratio_and_marginal_probabilities)?
