R help - Sep 2010 - cochran Q test

Dear all,

I am trying to look for a built in function that performs the cochran Q
test.
that is, cochranq.test(X)
where X is a contingency table (maybe a matrix or data.frame).
The output will naturally be the test statisitcs, p-value, etc.

A quick search on Google gives me the cochran.test in the 'outlier'
package,
but I had a look at the description of the test and it doesn't look anything
close to the cochran Q test.

MY questions is:
1. Is that cochran.test the cochran Q test I am looking for?
2. If not, where can I find such function? I DON'T want to write my own
function.

Thanks

THanks for all the replies.
I guess I should have been clearer from the beginning. 
When I said I don't want to write my code, I meant I don't want to
CREATE a new function.
Not because I can't, but because I don't want to.

The cmh.test in the {lawstat} package still doesn't look like the cocrahnQ
test to me. Maybe I am wrong?

you want something more 'official', whatever that means, look at the
Cochran-Mantel-Haenzel test, of which Cochran's Q is a special case:
