Source: R/remove_elements.R
remove_elements.Rd

Splits a character vector into the elements that match a removal set and those that remain. Used to peel salutations, suffixes, and status flags off a name vector during parsing.

Usage

remove_elements(x, elements)

Arguments

x

A character vector to filter.

elements

A character vector of values to remove from x.

Value

A list with two components: names (the elements of x that were not removed) and removed_names (the removed elements collapsed into a single underscore-separated string, or "" when nothing matched).

Examples

x <- c("MICHAEL", "JOHN", "LIVINGSTON", "III")
remove_elements(x, c("JR", "II", "III", "IV"))
#> $names
#> [1] "MICHAEL"    "JOHN"       "LIVINGSTON"
#> 
#> $removed_names
#> [1] "III"
