I have a 5 X 6 contingency table, with zeros in 14 of the 30 cells:
Given that the expected values of most of the cells is smaller than 5, I try to run a Fisher exact text (instead of a chi-square test), but get the following error:
How should I go about determining statistical significance with regards to independence of these two categorical variables?

Maybe the problem is that your input is a data frame?

Well, that's embarrassing. Yeah, that was the problem. Thanks.
I just discovered data.matrix(), which converts from type data.frame to matrix.
