Vectorised over `string`

and `pattern`

.

`str_split(string, pattern, n = Inf, simplify = FALSE)`str_split_fixed(string, pattern, n)

string

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
`regex()`

.

Match a fixed string (i.e. by comparing only bytes), using
`fixed()`

. This is fast, but approximate. Generally,
for matching human text, you'll want `coll()`

which
respects character matching rules for the specified locale.

Match character, word, line and sentence boundaries with
`boundary()`

. An empty pattern, "", is equivalent to
`boundary("character")`

.

n

number of pieces to return. Default (Inf) uses all possible split positions.

For `str_split_fixed`

, if n is greater than the number of pieces,
the result will be padded with empty strings.

simplify

If `FALSE`

, the default, returns a list of character
vectors. If `TRUE`

returns a character matrix.

For `str_split_fixed`

, a character matrix with `n`

columns.
For `str_split`

, a list of character vectors.

`stri_split()`

for the underlying implementation.
