Hello everyone:

I want to do the following :

sort year state cnum votes

by year stata cnum votes : keep if _n==_N

That way I get the guy with the max no of votes.

Now when I do this for 1 or 2 arguments for by then it works, but not
for 4 arguments I have . Does by have a limit on how many arguments it
can have ?

I read -help by- and that does mention using by in the following
fashion : -- > by year ( state) . Do I need to put in brackets for the
other arguments?

Could someone please clarify?

Thank you,
Ashim.
