leaflet.extras (development version)

leaflet.extras 2.1.0

CRAN release: 2026-09-16

New Features

• addGeoJSONChoropleth() / addKMLChoropleth() can vary polygon fill opacity per feature via fillOpacityProperty (property name or JS function). Passing a JS function as fillOpacity works too. Fix #53
• addHeatmap and addWebGLHeatmap now scale intensity values so that raw weights such as 1 vs 500 stay visually distinct. Use scaleIntensity = FALSE for the previous clipping behavior. addHeatmap also sets maxZoom = 0 when scaling so Leaflet.heat does not fade points to blue at low zoom. New addHeatmapLegend() (also via legend = TRUE) adds a color guide. Fix #126, Fix #160
• Include the plugin leaflet-groupedlayercontrol. See the example in /inst/examples/shiny/groupedlayercontrol_app.R for a demo of all options and methods. Fix #202
• addGreatCircles() gained editable = TRUE to drag a radius handle on the circumference (as in the Leaflet.Geodesic interactive circle demo). showStats now reports radius and circumference; Shiny input MAPID_geodesic_stats includes radius. Fix #44

Improvements

• Updated GitHub Actions dependencies (actions/checkout v6, actions/setup-node v6, actions/cache v5, actions/upload-artifact v6, JamesIves/github-pages-deploy-action 4.7.6) and the npm js-yaml lockfile (4.1.1).
• Style GHA no longer runs on pull_request (detached HEAD made git pull fail after auto-commits). It now runs on push to the branch instead.
• pkgdown reference index includes addHeatmapLegend.

Bugfixes

• Rd examples no longer download GeoJSON from GitHub during R CMD check --as-cran (--run-donttest). CI failed with HTTP 429 (rate limit) on ubuntu-latest/oldrel-1. Examples now use local fixtures under inst/examples/data/geojson/.
• Tests no longer download example GeoJSON/TopoJSON from the defunct rawgit.com service. CRAN checks failed because those URLs were unreachable (test-geojson_mini.R, test-heatmaps.R). Local fixtures are used instead, and remaining rawgit links in examples/docs now point to raw.githubusercontent.com. Long example URLs in omnivore and webglheatmap docs are wrapped to stay under the Rd 100-character limit. Thanks @ngoodkind for reporting and opening #251. Fix #250
• New argument filtersearch for searchOptions to limit the Nominatim search area. Fix #168
• addSearchFeatures displays all matching results, even in the case of duplicates. However, markers and animations are currently only applied to a single result and not to all matching entries. Fix #150
• New argument fillColor for pulseIcons. Fix #231
• New argument group for addMeasurePathToolbar. Supports single group, multiple groups, or all layers (group = NULL). Fix #233
• addSearchGoogle / addReverseSearchGoogle load the Google Maps JavaScript API as an htmlDependency instead of htmlwidgets::appendContent(), which Shiny ignores (Ignoring appended content). The search control now appears in renderLeaflet(). Demo: /inst/examples/shiny/search/google_app.R. Fix #112
• Google and OSM search suggestions crashed or showed undefined because leaflet-search PR 339 called formatData(control, data) instead of formatData(data). Search formatters now accept both signatures, and Google results unwrap GeocoderResponse.results.
• addReverseSearchGoogle no longer reads minified Google LatLngBounds internals (viewport.f / viewport.b). Bounds use getSouthWest() / getNorthEast() (or south/west/north/east).
• addLatLng registers vertex markers in Leaflet’s marker category with the geodesic’s group and a unique layer id, and removes them when the line is deleted (removeShape / clearShapes / clearGroup). Hide/show by group still keeps them.

leaflet.extras 2.0.1

CRAN release: 2024-08-19

leaflet.extras 2.0.0

CRAN release: 2024-06-10

New Features

• addDrawToolbar offers some new options:
  • handlersOptions and toolbarOptions, with which you can customize the drawing toolbar and the tooltips
  • addDrawToolbar got a new argument drag. When set to TRUE, the drawn features will be draggable during editing, utilizing the Leaflet.Draw.Drag plugin. Otherwise, this library will not be included. Fix #115
• searchOSMText enables setting the OpenStreetMap (OSM) search text directly from R
• clearSearchOSM allows clearing the search marker associated with addSearchOSM. Fix #158, Fix #209
• clearSearchFeatures provides functionality to clear the search marker
• addReverseSearchOSM gained new arguments:
  • marker allows customization of the icon for the found feature
  • showFeatureOptions enables styling options for the found feature
  • showBoundsOptions allows customization of the style for the boundary of a found feature
  • showHighlightOptions enables customization of the hover effect for a found feature
• addBounceMarkers behave now like normal Markers (except for clustering)
• Update Geodesics functions to show default or custom statistics in Control Info, show (draggable) Markers, use layerManager, enable popup/label/markerOptions/highlightOptions, emit Mouse Events, accept icons.
• addLatLng for addGeodesicPolylines allows you to append line vertices
• Emit mouse events (click, mouseover, and mouseout) for drawn features. The event names are suffixed with identifiers based on the layercategory, appended with _draw_click, _draw_mouseover, or _draw_mouseout. The layercategory should be either shape, polyline, or marker. (Thanks to @cmcaine) See examples/shiny/draw-events/draw_mouse_events.R

Improvements

• The apikey of addSearchGoogle / addReverseSearchGoogle / addBingTiles now has to be not NULL and also not ""
• Extend BingTiles imagerySet and emit warnings for deprecated sets
• Changed default values in searchOptions for url / propertyLoc / propertyName
• Draw events trigger correctly using priority: "event". Fix #89
• Included 12 color gradients from colorbrewer2 for addWebGLHeatmap using this script /scripts/generate_color_gradients.R
• In addReverseSearchOSM, longitudes are now normalized to ensure that the Nominatim search returns features for wrapped tiles.
• Updated most JavaScript dependencies, changed Webpack Build, removed source-maps as package size was an R-CMD-check issue
• Include Tests for R functions
• Use Github Actions (R-CMD-check, pkgdown, test-coverage, NPM builds, Styler, PR-commands)
• Fixed & extended examples

Bugfixes

• #104, #148, #155, #156, #164, #165, #169, #174, #187
