str_extract_all {stringstatic}

Extract matching patterns from a string

Description

Dependency-free drop-in alternative for stringr::str_extract_all().

Usage

str_extract_all(string, pattern, simplify = FALSE)

Arguments

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 base::regex. Control options with regex().

Match a fixed string (i.e. by comparing only bytes), using fixed(). This is fast, but approximate.

simplify

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

Value

A list of character vectors if simplify = FALSE, or a character matrix if simplify = TRUE.
