Create Interactive Web Maps with the JavaScript Leaflet Library (original) (raw)

Leaflet is an open-source JavaScript library for interactive maps. This R package makes it easy to create Leaflet maps from R.

Installation

You can install this package from CRAN, or the development version from GitHub:

Development

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
