A Mapbox account and mapbox access token is required for Mapbox basemaps, with or without the Mapbox data service. See mapbox_access_token for usage.

{rdeck} draws much inspiration from kepler.gl and {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 with appropriate untransformed tick marks.
e.g. scale_color_power, scale_color_log etc.
Automatic creation of formatted tooltips
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.
