Description

A convenience function. Calls either stri_locate_all_regex, stri_locate_all_fixed, stri_locate_all_coll, or stri_locate_all_charclass, depending on the argument used.

Usage

stri_locate_all(str, ..., regex, fixed, coll, charclass)

Arguments

str

character vector of strings to search in

...

additional arguments passed to the underlying functions

regex

character vector; regular expressions

fixed

character vector; fixed patterns

coll

character vector; canonically equivalent patterns

charclass

character vector; identifiers of character classes
