multinomial test

Thanks. That is what I try to find. You know what, I have tried ?multinomial, but it didn't recognize. It is case sensitive I guess.

Qinghong:

R Has an extensive Help system which you should learn to use.

help.search('multinomial') 
?Multinomial

Jim: sample() is wrong -- it gives random samples, not probabilities.

?sample

sample(1:3, 6, TRUE, prob=c(2/9, 1/6, 11/18))

Hi All,

What is the R function for computing multinomial distribution, e.g.
f(2,1,3; 2/9, 1/6, 11/18, 6)?

That is, a total of 6 trials, event 1's p1=2/9, x1=2, event 

2's p2=1/6,

x2=1, and event 3's p3=11/18, x3=3.

thanks,
Johnny
