## leaflegend 1.0.0

• 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.

• 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.
