Dear list, I am trying to write a function that will make a matrix of each row of a data frame (4 columns), calculate a fisher.test on each resulting matrix and assign a vector of the p-values.

Hi - Wondering if someone could help me with a plotting problem. I looked through the postings for this error message but the explanations are hard to follow.
