[R] Exact test in nxm contingency table

[Søren Højsgaard]

Using r2dtable() you can simulate general tables nxm with given margins. Based on these you acn calculate a Monte Carlo p-value for a conditional test for independence.

Emne: [R] Exact test in nxm contingency table

Hello,

I am trying to find a permutation test that works on a general nxm table. The data set is small enough to have cells with too small counts to make chi2-approximation invalid. If the table was a 2x2 contingency table I would like to use a Fsher exact test (fisher.test) but that wont work in this general table.

Does there exist a general function for this test.

Best regards,

Magnus Pettersson
