tuplicate {tuple}

Find n-Replicated Elements

Description

Finds elements that occur exactly n times in a vector.

Usage

tuplicate(x, n)

Arguments

x

A vector.

n

An integer.

Details

Returns the n-replicated elements in the same order that they would be returned in a call to orphan. This fundamentally differs from tuplicated, which returns a logical vector that is TRUE when it runs into any but the (n-1)-st and fewer occurrences of an element (and is therefore dependent on the direction of testing of the vector).

Examples

x <- c(NA, 1:3, 4:5, rep(6, 6), 3, NA, 4, 3, 3)
lapply(2:6, function(X) { tuplicate(x, X) })
