Description

Split a string

Usage

1
str_split_one(string, pattern, n = Inf)

Arguments

string

A character vector with, at most, one element.

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.

Value

A character vector.
