Overview

About

Maintained by Garrick Aden-BuieCRAN page ↗GitHub ↗Website ↗Issues ↗Declared funder: Posit Software, PBC

Create and customize interactive maps using the 'Leaflet' JavaScript library and the 'htmlwidgets' package. These maps can be used directly from the R console, from 'RStudio', in Shiny applications and R Markdown documents.

Changes in 2.2.3

{leaflet} is now licensed under the MIT license (was GPL-2) (#958).
{leaflet} no longer install {sp} by default and attempts to convert object to sf internally before creating a map and warns when it fails conversion (@olivroy, #942).
The breweries91, atlStorms2005, and gadmCHE datasets are now {sf} objects (@olivroy, #944).
{leaflet} now requires R 3.5 and above (@olivroy, #944).
Color palette improvements. All color palette functions now support all {viridisLite} palettes ("magma", "inferno", "plasma", "viridis", "cividis", "rocket", "mako", and "turbo") (@jack-davison, #924).
Updated vignettes to replace {sp}/{raster} usage with {sf}/{terra} and their corresponding examples. (@jack-davison, #928)
Updated vignettes to replace {sp}/{raster} usage with {sf}/{terra} and their corresponding examples. (@jack-davison, #928)
addProviderTiles() will now error if the chosen provider does not match any currently loaded provider (by default, those in providers). This behaviour can be toggled off by setting the new check argument to FALSE (@jack-davison, #929)

From NEWS.md in the release

Install

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

install.packages("leaflet", 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("rstudio/leaflet")

Development version from rstudio/leaflet. 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-leaflet

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-leaflet

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-leaflet

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.
