Description Usage Arguments Value See Also Examples

This function uses fuzzy string matching to replace one possibly misspelled (or in other way not fully correct) character string with a correct version of the same string.

1	best_match(x, key, clean_text = TRUE, no_match = NA, all = FALSE)

`x`	is a character string (or a character vector) that should be matched to the `key`
`key`	is a vector containing the correct spellings of the character strings.
`clean_text`	(boolean of length one) should arguments `x` and `key` be passed to `clean_text` before matched (to ignore special characters)?
`no_match`	Output value if there is no match. Default is NA. The input is returned unchanged if not matched and no_match = NULL.
`all`	is a boolean indicator to specify what happens if there is more than one match. Default is `FALSE` resulting in a warning message and that only the first match is used. The result can then be returned as a vector. If `TRUE`, all possible matches are returned and the result must therefore be a list.

The function returns a character vector of the same length as x if all = FALSE but with each element substituted to its best match in the key-vector. Strings that could not be matched are NA if (no_match = TRUE) or unchanged if no_match = FALSE. If all = TRUE, one input character string could result in more than one output character string. The output might therefore be longer than the input.
