stringi (version 1.0-1)

stringi-search: String Searching

Description

This man page instructs how to perform string search-based operations in stringi.

Arguments

Details

The following independent string searching ``engines'' are available in stringi.

Each ``engine'' is able to perform many search-based operations. These may include:

  • stri_detect_*- detect if a pattern occurs in a string, see e.g.stri_detect,
  • stri_count_*- count the number of pattern occurrences, see e.g.stri_count,
  • stri_locate_*- locate all, first, or last occurrences of a pattern, see e.g.stri_locate,
  • stri_extract_*- extract all, first, or last occurrences of a pattern, see e.g.stri_extractand, in case of regexes,stri_match,
  • stri_replace_*- replace all, first, or last occurrences of a pattern, see e.g.stri_replaceand alsostri_trim,
  • stri_split_*- split a string into chunks indicated by occurrences of a pattern, see e.g.stri_split,
  • stri_startswith_*andstri_endswith_*detect if a string starts or ends with a pattern match, see e.g.stri_startswith,
  • stri_subset_*- return a subset of a character vector with strings that match a given pattern, see e.g.stri_subset.
