Hi Peter and Gerrit, Sorry about my confusion with the results I was not entirely sure what they were. I was expecting some form of a table and i didn't realize that with the results of a fisher test, one just gets a p-value. I had tried the 'estimate' and 'null.value' w

Paul, in addition to Peter's suggestion about the missing of theory you are also completely missing to explain what you mean by "[it] is not giving me the results for the calculations" or "[how] to get the results of the fisher test". They are there in the output of R's fisher.test() (if you h

Dear all, I am trying to do a fishers test on a 5x4 table on R statistics. I have already done a chi squared test using Minitab on this data set, getting a result of (1, N = 165.953, DF 12, p>0.001), yet using these results (even though they are excellent) may not be suitable for public
