Many, many thanks Eric!

Yes, -tabout- really seems to be much faster than -collapse-. However, I
could not figure out how to make it work when one has n categorical
variables, and wants to summarize continous variables taking all possible
combinations of the n categorical variables.

-collapse- does that using the by() option.

Thanks again!

Tiago

Dear Statalister,

I am eager to know any faster alternatives to -collapse-, because I have
to summarize relatively large data sets for a simulation study. -profiler-
is telling me that most of the computation burden comes from -collapse-.
Do you know (have) any faster alternative? Perhaps a plug-in?

Thanks!

Tiago
