Installing the Leaflet module
To install the module, download the latest release file from the github page:
Unzip the file so that all the files in the zip are in
a folder named modules/leaflet
in the root folder of your RPGM project.
You should have a modules/leaflet/main.R
file.
Open your ppro file and add the following lines in the Custom CSS/JS files field:
modules/leaflet/resources/leaflet.js
modules/leaflet/resources/leaflet.css
modules/leaflet/main.css
modules/leaflet/main.js
The module is installed!
