stri_locate: Locate Occurrences of a Pattern

In stringi: THE string processing package for R

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, 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
charclass	character vector; identifiers of character classes
mode	single string; whether to look for all, or only the first/last occurrence of the pattern

Details

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

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.
