Hi Chuck,
Thank you for the fast reply.
I looked through that thread (that's how I came across the commands I
wrote).

1) My question was if this command (cochran.test) could be used the same way
as (mcnemar.test). It obviously can't be, but maybe there is another command
I don't know about.
2) Why do you think I might not want this test ?

Thanks,
Tal
