[R] Difficulty with what is probably a basic function to retrieve data from a data frame.

[Ivan Calandra]

Hi,

First, if you want a precise answer, provide a precise question. That 
is, provide a reproducible example. A good function for that is dput(), 
with which you can copy/paste your own data. If your data is too long, 
create a relevant subset (with head() for example).

Regarding your question: are you looking for table()?

HTH,
Ivan
