And on mine (A: PII, Red Had 9, R-1.8.0): ff <- c(0,10,250,5000); dim(ff) <- c(2,2); 1-fisher.test(ff)$p.value [1] 1.268219e-11 (B: PIII, SuSE 7.2, R-2.1.0beta): ff <- c(0,10,250,5000); dim(ff) <- c(2,2); 1-fisher.test(ff)$p.value [1] -1.384892e-12 Peter, I'm not sure which is the more interesting!
