This is a generic function, with methods supplied for data frames and vectors. The default behavior counts the number of pairs of elements of
x. One can find the number of triples, etc., by changing the
nrep argument. If there are specific values for which one is looking for repeats, these can be specified with the
vals argument. Note that the function only checks for exactly
nrep instances, so two pairs of a specific element would be counted as 0 pairs and 1 quadruple. See the examples.
The data frame method uses

countrep.default to each row of the data frame.
x is a vector, then the value is an integer. If
x is a data frame then the value is a vector, with entries the corresponding value for the respective rows of
