stri_locate: Locate Occurrences of a Pattern

Description Usage Arguments Details Value See Also

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

1
2
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.
