Input vector. Either a character vector, or something coercible to one. |
pattern |
Pattern to look for. The default interpretation is a regular expression, as described
in stringi::stringi-search-regex. Control options with

For str_split_fixed
, a character matrix with n
columns.
For str_split
, a list of character vectors.
