Fast and Portable Character String Processing in R (with the Unicode ICU)

Build Status RStudio CRAN mirror downloads RStudio CRAN mirror downloads RStudio CRAN mirror downloads

A comprehensive tutorial and reference manual is available at https://stringi.gagolewski.com/.

Check out stringx for a set of wrappers around stringi with a base R-compatible API.

To learn more about R, check out Marek's open-access (free!) textbook Deep R Programming.

stringi (pronounced stringy, IPA [strini]) is THE R package for string/text/natural language processing. It is very fast, consistent, convenient, and thanks to the ICU International Components for Unicode library portable across all locales and platforms.

Available features include:

  • string concatenation, padding, wrapping,
  • substring extraction,
  • pattern searching (e.g., with Java-like regular expressions),
  • collation and sorting,
  • random string generation,
  • case mapping and folding,
  • string transliteration,
  • Unicode normalisation,
  • date-time formatting and parsing,

and many more.

Package Maintainer: Marek Gagolewski

Authors and Contributors: Marek Gagolewski, with contributions from Bartomiej Tartanus and many others.

The package's API was inspired by that of the early (pre-tidyverse; v0.6.2) version of Hadley Wickham's stringr package (and since the 2015 v1.0.0 stringr is powered by stringi).
