stri_locate: Locate Occurrences of a Pattern

Description

A convenience function. Calls either stri_locate_all, stri_locate_first, or stri_locate_last, depending on the argument used. Note that this is slower than the direct call.

Usage

stri_locate(str, ..., regex, fixed, coll, charclass, mode = c("first", "all",
  "last"))

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

mode

single string; whether to look for all, or only the first/last occurrence of the pattern

Value

• The return value is the same as that of the underlying functions called, i.e. a two-column matrix or a list of matrices.

Details

Unless you are very lazy, please call the underlying functions directly for better performance.
