addLegendNumeric now has the ability to use manual tick breaks and labels when the bins argument is a numeric vector greater than length 1. This only applies to vertically oriented legends.addLegendNumeric gains labelStyle argument and significant improvements to the layout that will handle larger font sizes and long text widths.
added stacked argument to addLegendSize to allow size legends that are more compact when symbols are overlayed. See examples in ?addLegendSize.
groups can now have underscores in their name for show/hide functionality.
added between argument to addLegendBin and addLegendQuantile so that users can change the dash.
fixed issue where addSymbols and addSymbolsSize only worked when directly specifying lat and lng. These now work for sf objects.
added dashArray argument for symbols functions. The main purpose is to allow dashed line encodings, but all symbols can have dashed outer lines.
updating test for ‘leaflet’ changes in v2.2.0
pch solid symbols 15-20 will use color if fillColor is missing
availableShapes is provided for convenience to look up supported symbol names.
addLegendFactor, addLegendBin, and addLegendQuantile will now show a symbol for missing values if they exist and gain the naLabel argument.
Label spacing adjustments for addLegendNumeric which should support longer labels.
addLegendNumeric gains an argument naLabel and now shows the NA color when there are missing values.
addLegendNumeric gains an argument labels which allows the user to pass label names for numeric breaks.
The breaks argument in addLegendLine and addLegendSize now allows the user to pass a named list where the names are the labels.
makeSymbol and makeSymbolIcons can now create map symbols that are consistent with base R pch. The shape argument can accept the name or an integer (0-indexed). availableShapes provides a list of named options.
A new function addLegendSymbol has been added to automatically encode character/factors as various map symbols.
The default argument for baseSize in addLegendSize has been changed to 20.
values argument is no longer used by addLegendBin since it is not necessary and causes problems when number of values is less than the number of bins.
Updated example in README
Documentation has been updated for makeSymbols and the name has been changed to mapSymbols with some additional functions added to it.
Internal functions have been renamed to match naming conventions.
Renamed makeSizeIcons to makeSymbolsSize to be consistent in naming conventions. The colorValues argument has been removed. For the same functionality, specify a vector of color and fillColor.
Fixed issue with image styling missing for raster images in addLegendImage
Added functions to automate the task of creating map symbols. addSymbols will create map symbols based on a character or factor vector. addSymbolsSize will create map symbols with a size encoding.
Code re-factoring for addLegendBin, addLegendQuantile, and addLegendFactor as grouping of values for each is different but the assembly of the HTML is the same.
Unit tests have been added to cover all the current functions.
Gradient IDs for numeric legends are now based on the function call or data “name” in values.
makeSizeIcons default opacity is now 1.
Adding internal functions to add dependencies for addLegendAwesomeIcon. Awesome Icons would not show in legends because the needed HTML dependencies were not loaded unless addAwesomeIcons was included. addLegendAwesomeIcon will now check if the dependencies are in the “leaflet” map and include them if missing.
Added error messages for invalid width, height, tickWidth, tickLength, and strokeWidth arguments. Prior to this negative values would not throw errors and the visual output of legends was not desirable.
Ability to specify values parameter as a formula to retrieve from the data argument which is the same as the “leaflet” package.
makeSymbolIcons now supports vectorization for multiple shape arguments
Awesome icons are now centered in a marker in addLegendAwesomeIcon
adding support for text parameter passed to addLegendAwesomeIcon. This allows an svg to be passed to as an icon.
patching examples that use png files from leaflet js site since they have moved.
adding leaf images png files for examples
updated layers control to handle special characters in group name. All non-alphanumeric characters are removed from the class names and javascript selectors.
added better error message for missing color and pal
adding addLegendLine to add height only encoding of size based on values
updated example in README
adding addLegendAwesomeIcon function to produce legends with markers from awesome icon libraries
adding in line and polygon symbol and adding symbols to the README
fixes error on makeSizeLegend where fillColor is not evaluated if no argument is provided
adding colorValues as an argument to makeSizeLegend so that symbols can be sized and colored on different vectors of data
fixes warning on addLegendNumeric where the shape default was a vector not a single value
adding number formatting to addSizeLegend
adding group layer support for legends. Use addLayersControl to turn on/off legends
added example for using raster images with size encodings based on data
stroke outlines of shapes are now padded so that the stroke is not cut off
numeric legends now have appropriate sizing for text
star symbol outline has been fixed
new function makeSizeIcons as a convenience wrapper size scaled symbols
new functions addLegendSize, sizeNumeric, and sizeBreaks were added to allow encoding size on symbols.
addLegendImage supports multiple height and width parameters for images where you want different sizes
addLegendImage now supports using an svg URI from the output of makeSymbol. To supply a custom svg URI, add the ‘svgURI’ class to the character vector.
added more shapes to makeSymbol, addLegendNumeric, addLegendQuantile, addLegendFactor, addLegendBin
Control the opacity of the legend shapes for addLegendNumeric, addLegendQuantile, addLegendFactor, addLegendBin
makeSymbol now returns embeddable svg
