## Installation

```r

# install latest release

remotes::install_github("qfes/rdeck@*release")

# or install development version

remotes::install_github("qfes/rdeck")

```

## Mapbox access token

A [Mapbox account](https://account.mapbox.com/auth/signup) and 

[mapbox access token](https://docs.mapbox.com/help/glossary/access-token) 

is required for Mapbox basemaps, with or without the Mapbox data service. 

See [`mapbox_access_token`](https://qfes.github.io/rdeck/reference/mapbox_access_token.html) for usage.

## Similar work

`{rdeck}` draws much inspiration from [`kepler.gl`](https://github.com/keplergl/kepler.gl) and 

[`{mapdeck}`](https://github.com/SymbolixAU/mapdeck). `{rdeck}`'s design choices make it convenient 

for use in static reports, and certain Shiny usecases that are highly performant.

Some notable differences to `{mapdeck}`:

* `{rmarkdown}` HTML reports made with `{rdeck}` are typically an order of magnitude smaller in file size than `{mapdeck}`. Thanks to: 

  - column-major data storage

  - client-side visual attributes scaling

  - client-side tooltip formatting

  - automatic filtering of data that is not used in the map

* Tidy evaluation is supported for column specifications.

* Extensive validation of layer properties in R is preferred, rather than throwing errors in the browser.

* `{ggplot2}` style `scale_` functions that perform common layer data transformations and automatically generate [legends](https://qfes.github.io/rdeck/reference/scale.html#legend) with appropriate untransformed tick marks.

  - e.g. `scale_color_power`, `scale_color_log` etc.

* Automatic creation of formatted [tooltips](https://qfes.github.io/rdeck/reference/tooltip.html)

* Choice of light or dark themes for tooltips and legends.

* Auto-generated interface from JS source

  - every deck.gl layer is supported to some degree

  - every layer property is a snake_case version of the camelCase deck.gl counterpart.

* Users can orchestrate browser-side map layer updates with Shiny, allowing for extremely performant reactivity.

  - Traditional Shiny interactivity using whole datasets is also possible, and is slightly slower than `{mapdeck}` at present.
