Overview

About

Maintained by Hadley WickhamCRAN page ↗GitHub ↗Website ↗Issues ↗Declared funder: Posit Software, PBC

A consistent, simple and easy to use set of wrappers around the fantastic 'stringi' package. All function and argument names (and positions) are consistent, all functions deal with "NA"'s and zero length vectors in the same way, and the output from one function is easy to feed into the input of another.

Changes in 1.6.0

Breaking changes

All relevant stringr functions now preserve names (@jonovik, #575).
str_like(ignore_case) is deprecated, with str_like() now always case sensitive to better follow the conventions of the SQL LIKE operator (@edward-burn, #543).
In str_replace_all(), a replacement function now receives all values in a single vector. This radically improves performance at the cost of breaking some existing uses (#462).

New features

New vignette("locale-sensitive") about locale sensitive functions (@kylieainslie, #404)
New str_ilike() that follows the conventions of the SQL ILIKE operator (@edward-burn, #543).
New str_to_camel(), str_to_snake(), and str_to_kebab() for changing "programming" case (@librill, #573 + @arnaudgallou, #593).

Minor bug fies and improvements

str_* now errors if pattern includes any NAs (@nash-delcamp-slp, #546).
str_dup() gains a sep argument so you can add a separator between every repeated value (@edward-burn, #564).
str_sub<- now gives a more informative error if value is not the correct length.

Show all changes in 1.6.0Hide the rest of the changes in 1.6.0

str_view() displays a message when called with a zero-length character vector (@LouisMPenrod, #497).
New [[.stringr_pattern method to match existing [.stringr_pattern (@edward-burn, #569).

From NEWS.md in the release

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("stringr", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("tidyverse/stringr")

Development version from tidyverse/stringr. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-stringr

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-stringr

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-stringr

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
