I do not manage to make a Fisher´s exact test with the next matrix : [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [,11] [,12] [1,] 1 3 0 1 2 9 0 0 2 5 8 6 [2,] 0 3 3 0 0 0 0 5 0 3 0 0 [3,] 0 0 0 0 0 10 0 0 0 0 10 0 [4,] 0 2 0 2 6 14 0 0 6 0 10 6 [5,] 0 5 0 0 0 7 0 0 0 2 8 0 [6,] 0 0 1 9 4 7 2 1 4 2 12 5 [7,] 0 6 0 0 0 0 0 0 0 5 1 3
but I do not understand why it does not work since I obtain the next error message : > fisher.test(enfin.matrix) Error in fisher.test(enfin.matrix) : Bug in FEXACT: gave negative key thank you for considering my application cédric finet ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
