leaflet 2.2.1

CRAN release: 2023-11-13

leaflet 2.2.0

CRAN release: 2023-08-31

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

leaflet 2.1.2

CRAN release: 2023-03-10

Bug fixes and improvements

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

leaflet 2.1.1

CRAN release: 2022-03-23

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

CRAN release: 2022-02-16

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#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

CRAN release: 2021-01-07

Features

  • Updated proj4.js to 2.6.2

CRAN release: 2019-11-16

Breaking changes

Bug fixes and improvements

  • 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

CRAN release: 2018-06-04

Features

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)

  • Use correct Leaflet.js scale control remove method. (#547)

leaflet 2.0.0

CRAN release: 2018-04-20

Breaking changes

Bug fixes and features

  • Added more providers for addProviderTiles(): “OpenStreetMap.CH”, “OpenInfraMap”, “OpenInfraMap.Power”, “OpenInfraMap.Telecom”, “OpenInfraMap.Petroleum”, “OpenInfraMap.Water”, “OpenPtMap”, “OpenRailwayMap”, “OpenFireMap”, “SafeCast”. (4aea447)

  • L.multiPolyline was absorbed into L.polyline, which accepts multiple an array of polyline information. https://web.archive.org/web/20220702182250/https://leafletjs.com/reference-1.3.4.html#polyline. (#515)

  • Fix bug where icons where anchored to the top-center, not center-center (2a60751)

  • Add groupOptions function. Currently the only option is letting you specify zoom levels at which a group should be visible.

  • Fix bug with accessing columns in formulas when the data source is a Crosstalk SharedData object wrapping a spatial data frame or sf object.

  • Fix strange wrapping behavior for legend, especially common for Chrome when browser zoom level is not 100%.

  • Fix incorrect opacity on NA entry in legend. (PR #425)

  • Added support for drag events (#405)

  • Ensure type safety of .indexOf(stamp) (#396)

  • validateCoords() warns on invalid polygon data (#393)

  • Added method argument to addRasterImage() to enable nearest neighbor interpolation when projecting categorical rasters (#462)

  • Added an 'auto' method for addRasterImage(). Projected factor results are coerced into factors. (9accc7e)

  • Added data parameter to remaining addXXX() methods, including addLegend. (f273edd, #491, #485)

  • Added preferCanvas argument to leafletOptions() (#521)

  • Added support for Crosstalk (https://rstudio.github.io/crosstalk/).

  • Added option to highlight polygons, polylines, circles, and rectangles on hover (use highlightOptions parameter).

  • 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
