Duplicate values.

Description

Extensions of duplicated. Logically and numerically index duplicate values.

Usage

dups(...)

idups(x, int = F)

Arguments

...	One or more atomic vectors to be evaluated for duplicated values.
x	An atomic vec.
int	TRUE or FALSE indicating whether to return a logical vector (int = FALSE) or an integer vector (int = TRUE).

Details

idups	Indexes all elements of x that are duplicates of its earlier element, either as a logical vector of the same length as x (when int = FALSE) or as an integer vector whose length is the same as the number of elements in x that are duplicates of earlier elements (when int = TRUE).
dups	Atomizes ..., then reduce the resulting vector to contain one copy of each duplicated element.

Value

A logical vector (when ⁠int = FALSE)⁠

idups

An integer vector (when ⁠int = TRUE⁠)

idups

An atomic vector

Examples

idups(c(0:5, 5:10, 10:15, 15:20), int = T)
