Conveniently add Icon Attributions to a Leaflet Map

Adds a short character string to the bottom-right of the map widget with the attribution and license of an icon library. group and layerId can be used to add or remove the attribution - e.g., if the markers using magicIcons() are hidden.

Usage

addIconAttribution(map, library = "fontawesome", layerId = NULL, group = NULL)

Arguments

map

a map widget object created from leaflet()

library

One of "fontawesome", "bootstrap", or "ionicons", defining the icon library of interest. Defaults to "fontawesome".

layerId

the layer id

group

the name of the group the newly created layers should belong to (for clearGroup and addLayersControl purposes). Human-friendly group names are permitted–they need not be short, identifier-style names. Any number of layers and even different types of layers (e.g. markers and polygons) can share the same group name.
