String Searching


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


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_extract and, in case of regexes, stri_match,

  • stri_replace_* - replace all, first, or last occurrences of a pattern, see e.g. stri_replace and also stri_trim,

  • stri_split_* - split a string into chunks indicated by occurrences of a pattern, see e.g. stri_split,

  • stri_startswith_* and stri_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.
