Re: st: Count observations

["Miguel Angel Duran Munoz" <maduran@uma.es>]

Hi, Statalisters. I have the following doubt. My dataset is arranged in
the following way. I have a variable that identifies firms (say id).
Another variable describes whether different types of fees (eg, A B C)
applies to a firm. Accordingly, the dataset looks similar to

Id    Type-of-fee

1          A
1          B
1          C
2          C
2          A
3          A
4          B
4          .
4          A

I would like to know, for instance, the number of A fees that there are. I
have used -count- but I am not able to get what I want. Will you please
help me?

Thanks in advance.

Miguel.
