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.
