Description Usage Arguments Value Examples

Do any of lvls occur in f? Compared to %in%, this function validates lvls to ensure that they're actually present in f. In other words, x %in% "not present" will return FALSE, but fct_match(x, "not present") will throw an error.

1	fct_match(f, lvls)

`f`	A factor (or character vector).
`lvls`	A character vector specifying levels to look for.
