Arguments

`map`	the leaflet map widget
`geojson`	a GeoJSON/TopoJSON URL or file contents in a character vector.
`layerId`	the layer id
`group`	the name of the group this raster image should belong to (see the same parameter under `addTiles`)
`markerType`	The type of marker. either 'marker' or 'circleMarker'
`markerIcons`	Icons for Marker. Can be a single marker using `makeIcon` or a list of markers using `iconList`
`markerIconProperty`	The property of the feature to use for marker icon. Can be a JS function which accepts a feature and returns an index of `markerIcons`. In either case the result must be one of the indexes of markerIcons.
`markerOptions`	The options for markers
`clusterOptions`	if not `NULL`, markers will be clustered using Leaflet.markercluster; you can use `markerClusterOptions()` to specify marker cluster options
`clusterId`	the id for the marker cluster layer
`labelProperty`	The property to use for the label. You can also pass in a JS function that takes in a feature and returns a text/HTML content.
`labelOptions`	A Vector of `labelOptions` to provide label
`popupProperty`	The property to use for popup content You can also pass in a JS function that takes in a feature and returns a text/HTML content.
`popupOptions`	A Vector of `popupOptions` to provide popups
`stroke`	whether to draw stroke along the path (e.g. the borders of polygons or circles)
`color`	stroke color
`weight`	stroke width in pixels
`opacity`	stroke opacity (or layer opacity for tile layers)
`fill`	whether to fill the path with color (e.g. filling on polygons or circles)
`fillColor`	fill color
`fillOpacity`	fill opacity
`dashArray`	a string that defines the stroke dash pattern
`smoothFactor`	how much to simplify the polyline on each zoom level (more means better performance and less accurate representation)
`noClip`	whether to disable polyline clipping
`pathOptions`	Options for shapes
`highlightOptions`	Options for highlighting the shape on mouse over. options for each label. Default `NULL` you can use `highlightOptions()` to specify highlight options
`title`	An optional title for the legend
`position`	legend position
`locale`	The numbers will be formatted using this locale
`numberFormatOptions`	Options for formatting numbers
`valueProperty`	The property to use for coloring
`scale`	The scale to use from chroma.js
`steps`	number of breakes
`mode`	q for quantile, e for equidistant, k for k-means
`channelMode`	Default 'rgb', can be one of 'rgb', 'lab', 'hsl', 'lch'
`padding`	either a single number or a 2 number vector for clipping color values at ends.
`correctLightness`	whether to correct lightness
`bezierInterpolate`	whether to use bezier interpolate for determining colors
`colors`	overrides scale with manual colors
`legendOptions`	Options to show a legend.
`kml`	a KML URL or contents in a character vector.
`latfield`	field name for latitude
`lonfield`	field name for longitude
`delimiter`	field seperator
`csv`	a CSV URL or contents in a character vector.
`csvParserOptions`	options for parsing the CSV. Use `csvParserOptions`() to supply csv parser options.
`gpx`	a GPX URL or contents in a character vector.
