# Frequencies

With the plyr package, use the count() function (via).

This code computes the frequencies for each value that var can take:

count(df, var)


If you want to have the frequencies of the combination of all the values of two variables, use this:

count(df, var1, var2)


If R does not display all the rows, use this:

as.data.frame(count(df, var1, var2)
