## Installation

``` r
install.packages("leafdown")
```
You can install the development version from [GitHub](https://github.com/) with:

```
## Documentation
You can find the documentation [here](https://hoga-it.github.io/leafdown/index.html).
## Features
- Adds drilldown functionality for [leaflet choropleths](https://rstudio.github.io/leaflet/choropleths.html) maps.
- Allows the selection of regions/shapes.
- Easy to use and well-integrated into syntax of the [leaflet](https://rstudio.github.io/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.
## Showcase - Election Map
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.
Click here for the [full demo app](https://pega.shinyapps.io/election16/) and here for the [documentation](https://hoga-it.github.io/leafdown/articles/Connection_to_other_elements.html).
## Showcase - healthdown
The healthdown app allows interactive comparison of various health factors at the U.S. state and county level.
It was honored as "Runners up" in the Shiny Contest 2021.

## Showcase - Weather stations
This app allows interactive comparison of weather station measurements between states, counties and individual stations.
It was primarily developed for Andreas' [talk](https://www.rstudio.com/conference/2022/talks/leafdown-interactive-multi-layer-maps/)
at the rstudio::conf(2022), where he demonstrated the capabilities of the leafdown package.
