re_split: Split a string by a regular expression pattern

Description

re_split splits each element of a character vector into substrings based on a specified pattern (regular expression). If the provided pattern is not already a compiled pattern object, it compiles it using re_compile. The function allows for controlling the maximum number of splits performed.

Usage

re_split(pattern, string, ..., maxsplit = -1L)

Value

A list of character vectors, where each vector contains the substrings resulting from splitting the corresponding element of string.

Arguments

pattern

A regular expression pattern or a compiled pattern object.

string

A character vector where each element is a string to be split.
