In rematch: Match Regular Expressions with a Nicer 'API'

Extract all matches of a regular expression

Description

This function is a thin wrapper on the gregexpr base R function, to provide an API that is easier to use. It is similar to re_match, but extracts all matches, including potentially named capture groups.

Usage

re_match_all(pattern, text, ...)

Arguments

pattern	Regular expression, defaults to be a PCRE expression. See regex for more about regular expressions.
text	Character vector.
...	Additional arguments to pass to regexpr.

Value

A list of character matrices. Each list element contains the matches of one string in the input character vector. Each matrix has a .match column that contains the matching part of the string. Additional columns are added for capture groups. For named capture groups, the columns are named.
