Thanks Jim. I think my previous posting wasn't clear enough. What I try to do is to compute the probability: f(2,1,3; 2/9, 1/6, 11/18, 6). (If we compute by hand, it is 0.1127). What is the R funtion for doing that? I know for binomial tests, there is a function called binom.test. But for multinomial events, is there a similar function in R? thanks Johnny
