There are several such lists. The one you want is probably the one
the help system uses. For example,
lists a number of functions that count various things. I don't think
any of them is exactly what you want, which could be accomplished in a
couple of ways:
gives counts of all the different values in x;
gives the count of occurences of 3 in x.
