In leaflet: Create Interactive Web Maps with the JavaScript 'Leaflet' Library

leaflet 2.2.2

• Fixed #893: Correctly call terra::crs() when checking the CRS of a SpatVector object in pointData() or polygonData() (thanks @mkoohafkan, #894).
• {leaflet} now has a brand new pkgdown site (@olivroy, #902)

• Replace {viridis} dependency by {viridisLite} (@olivroy, #897)

• addRasterImage now takes options = gridOptions(), so that arbitrary Leaflet layer options can be controlled. (#692)

leaflet 2.2.1

• When addProviderTiles() is used with {leaflet.providers} version 2.0.0 or later, the leaflet-providers HTML dependency produced can be correctly cached by knitr. When used with older versions of {leaflet.providers}, the HTML dependency uses temp files that break knitr's caching mechanism (thanks @qdread, @jaredlander; #884).

leaflet 2.2.0

Features

• Added support for SpatRaster and SpatVector objects from the terra package. (#728)

• leaflet() now uses jQuery 3.6.0 provided via the {jquerylib}package. As a result of this change, the HTML dependencies for leaflet() are included in the dependencies item of the htmlwidget object it returns. (#817, #821)

Bug fixes and improvements

• Use correct license in OpenStreetMap attribution. (#811)

• Use xfun::base64_uri() for base64 encoding instead of markdown and base64enc. (#823)

• Remove dependencies on rgdal and rgeos. (#837)

• Respect option scrollWheelZoom=FALSE. (#827)

• Fixed #866: Correctly call terra::has.RGB() in addRasterImage() for a SpatRaster object. (#869)

leaflet 2.1.2

Bug fixes and improvements

• Removed S3 warnings found on R devel (#848)

leaflet 2.1.1

Bug fixes and improvements

• The default marker icon for addMarkers no longer worked, due to the CDN we were relying on apparently being retired. Fixed by pointing to a new CDN. (#782)

• New behavior from tile.openstreetmap.org caused addTiles default tileset to break when viewed under non-https protocol on recent versions of Chrome. Fixed by always using the https protocol to connect to openstreetmap. (#786)

leaflet 2.1.0

Bug fixes and improvements

• Enable JS function literals (wrapped in htmlwidgets::JS()) to be included in arguments to methods invoked on leafletProxy objects. (JS function literals could already be included with methods invoked on leaflet objects, so this change just brings leafletProxy to parity.) (#420)

• Add missing CSS rule to show <img> in right-pane and left-pane (rstudio/rmarkdown/issues#1949, #770)

• Allow for hidden but not suspended leaflet maps to queue calls (such as add raster images) until they are rendered. If a new leaflet map is created, all pending calls are removed. (#771)

leaflet 2.0.4.1

Features

• Updated proj4.js to 2.6.2

Bug fixes and improvements

• Minor tweaks to example data and tests, required to stay on CRAN

• Fixes broken URL (#742) and updated examples to run from system files (#576) including updated .Rmd and .html docs.

leaflet 2.0.3

Breaking changes

• data("providers") and data("providers.details") no longer exist. Please use leaflet::providers and leaflet::providers.details. (#636)

Bug fixes and improvements

• Integrated data from leaflet.providers package. See leaflet.providers for details. (#636)
• Fixed rstudio/crosstalk#58, which caused Leaflet maps that used Crosstalk shared data in Shiny apps, to be redrawn at incorrect times.
• invokeRemote() now resolves html dependencies before passing them to shiny::createWebDependency() (#620).
• Upgrade leaflet-provider to 1.4.0, enable more map variants such as CartoDB.Voyager (#567)
• sf objects with names attributes in the st_geometry now visualise correctly (#595)
• GeoJSON objects missing properties can now be displayed (#622)

leaflet 2.0.2

Bug fixes and improvements

• Require viridis >= 0.5.1 to avoid namespace issues with viridisLite (#557)
• Fixed broken mouse events after using leaflet-search from leaflet.extras within shiny applications (#563)
• Use leaflet namespace on providers in addMiniMap to make the function accessible in other packages. Fixes r-tmap/tmap#231. (#568)
• Require scales >= 1.0.0 to avoid exact color matching issues (#578)

leaflet 2.0.1

Features

• Added method addMapPane to add custom pane layers to have fine tune control over layer ordering. New feature from within leaflet.js v1.x. (#549)
• Exposed htmlwidgets sizingPolicy in leaflet() (#548)

Bug fixes and improvements

• Default marker icon locations will now use unpkg.com instead of the leaflet cdn when using https or file protocols. (#544)
• .leaflet-map-pane z-index switched to 'auto'. Allows for map panes to appear above the map if they appear later in the dom. (#537)
• Use correct Leaflet.js scale control remove method. (#547)
• Start from world view if using flyTo or flyToBounds. (#552)

• colorFactor no longer interpolates qualitative RColorBrewer palettes, unless the number of factor levels being mapped exceeds the number of colors in the specified RColorBrewer palette. (Issue #300)

• Upgrade leaflet.js to 0.7.7.1 (PR #359)

• Added a way for the Map instance to be instantiated via a factory.

leaflet 1.0.2

• When used with leafletProxy, fitBounds did not return its input object as output, so magrittr chains would break after fitBounds was called.
