end
input str2 fee

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.
