match_arg: Argument Matching

Description

See strex::match_arg().

Usage

match_arg(arg, choices = NULL, index = FALSE, several_ok = FALSE,
  ignore_case = FALSE)
str_match_arg(arg, choices = NULL, index = FALSE, several_ok = FALSE,
  ignore_case = FALSE)

Arguments

arg

A character vector (of length one unless several_ok = TRUE).

choices

A character vector of candidate values.

index

Return the index of the match rather than the match itself?

several_ok

Allow arg to have length greater than one to match several arguments at once?

ignore_case

Ignore case while matching. If this is TRUE, the returned value is the matched element of choices (with its original casing).
