WebFeb 11, 2015 · The ultimate goal here is to perform pair-wise fisher tests (using fisher.test ()) on each column and row between each of the data.frames. As an output I'd would like to create a table contain the resulting p-values from each pair-wise comparison corresponding to each row name, e.g.: Web1 is then a valid combination test. The Fisher Combination Test is an example of this; first, we map ponto the positive real line by the mapping p7!2 P i2I logp i, which is then transformed back onto the unit interval using the CDF of a ˜2 2jIj-distribution. Another simple way of constructing valid combination tests is to use the minimal p-value
