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).
