The leafdown package provides drilldown functionality for leaflet choropleths in R Shiny apps.

install.packages("leafdown")You can install the development version from GitHub with:
# install.packages("devtools")
devtools::install_github("hoga-it/leafdown")You can find the documentation here.
- Adds drilldown functionality for leaflet choropleths maps.
- Allows the selection of regions/shapes.
- Easy to use and well-integrated into syntax of the leaflet R package.
- Allows communication of the map with other shiny elements (e.g. graphs).
- Computationally efficient as drilldown is only executed for selected regions of interest.
To showcase the features of the leafdown package we have created a
demo app.
This app shows the 2016 us presidential election results as well as some
demographic information.

This app allows interactive comparison of weather station measurements between states, counties and individual stations. It was primarily developed for Andreas’ talk at the rstudio::conf(2022), where he demonstrated the capabilities of the leafdown package.
