.

`x` |
an object in which repeats should be counted. |

`vals` |
values that may be repeated. |

`nrep` |
exact number of repeats desired, defaults to pairs. |

`...` |
further arguments to be passed to or from other methods. |

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 `apply`

to apply `countrep.default`

to each row of the data frame.

If `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 `x`
