Hi

I have a panel that contains 16030 different ids per 28 countries. I
would like to know how many different ids do I have per country,
because not all the ids are available in all countries. I have tried
the command:

by country: egen tag=tag(id)

But tag is not compatible with by. Does anybody know any easy way of doing this?

Thanks,
Estrella
