deduplicate {tractor.base}

Concatenate and deduplicate vectors

Description

This function returns its arguments, after concatenating them using c and then removing elements with duplicate names. The first element with each name will remain, possibly with subsequent elements' content appended to it. Unnamed elements are retained.

Usage

deduplicate(..., merge = FALSE)

Arguments

...

One or more vectors of any mode, usually named.

merge

If FALSE, the default, duplicate elements will simply be discarded. If TRUE, additional elements with the same name will be appended to the retained one. This does not apply to unnamed elements. If this kind of deduplication actually happens, the return value will be a list, regardless of the source type.

Value

The concatenated and deduplicated vector.
