Locate Occurrences of a Pattern

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
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.
