Leaflet is an open-source JavaScript library for interactive maps. This R package makes it easy to create Leaflet maps from R.
library(leaflet) m = leaflet() %>% addTiles() m # a map with the default OSM tile layer m = m %>% setView(-93.65, 42.0285, zoom = 17) m m %>% addPopups(-93.65, 42.0285, 'Here is the <b>Department of Statistics</b>, ISU')
You can install this package from CRAN, or the development version from GitHub:
# CRAN version
install.packages('leaflet')
# Or Github version
if (!require('devtools')) install.packages('devtools')
devtools::install_github('rstudio/leaflet')
In addition to the usual R package documentation, we also have extensive docs and examples at: https://rstudio.github.io/leaflet/
leaflet's JavaScript build tools use Node.js, along with yarn to manage the JavaScript packages.
Install yarn using the official instructions.
You can test that Node.js and yarn are installed properly by running the following commands:
node --version yarn --version
To make additions or modifications to the JavaScript htmlwidgets binding layer, you must have all Node.js dependencies installed. Now you can build/minify/lint/test using yarn build, or run in "watch" mode by just running yarn watch. JS sources go into javascript/src and tests go into javascript/tests.
# install dependencies yarn # compile yarn build # watch yarn watch
