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
