Calculates relative frequencies of the rows of a data frame.
a data frame.
The function works by adding a
probs column to
x with equally likely entries of 1/n, where n is the number of rows. Then it aggregates the duplicated rows of
x while accumulating the probabilities associated with each.
A data frame formed by aggregating the rows of
probs column is added giving the relative frequencies of each of the rows.
