Graphics elements and layers

Add graphics elements and layers to the map widget.

Usage
addControl(map, html, position = c("topleft", "topright", "bottomleft", "bottomright"), 
    layerId = NULL, className = "info legend", data = getMapData(map))

addTiles(map, urlTemplate = "http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png", attribution = NULL, layerId = NULL, group = NULL, options = tileOptions())

addWMSTiles(map, baseUrl, layerId = NULL, group = NULL, options = WMSTileOptions(), attribution = NULL, layers = "")

addPopups(map, lng = NULL, lat = NULL, popup, layerId = NULL, group = NULL, options = popupOptions(), data = getMapData(map))

addMarkers(map, lng = NULL, lat = NULL, layerId = NULL, group = NULL, icon = NULL, popup = NULL, options = markerOptions(), clusterOptions = NULL, clusterId = NULL, data = getMapData(map))

addCircleMarkers(map, lng = NULL, lat = NULL, radius = 10, layerId = NULL, group = NULL, stroke = TRUE, color = "#03F", weight = 5, opacity = 0.5, fill = TRUE, fillColor = color, fillOpacity = 0.2, dashArray = NULL, popup = NULL, options = pathOptions(), clusterOptions = NULL, clusterId = NULL, data = getMapData(map))

addCircles(map, lng = NULL, lat = NULL, radius = 10, layerId = NULL, group = NULL, stroke = TRUE, color = "#03F", weight = 5, opacity = 0.5, fill = TRUE, fillColor = color, fillOpacity = 0.2, dashArray = NULL, popup = NULL, options = pathOptions(), data = getMapData(map))

addPolylines(map, lng = NULL, lat = NULL, layerId = NULL, group = NULL, stroke = TRUE, color = "#03F", weight = 5, opacity = 0.5, fill = FALSE, fillColor = color, fillOpacity = 0.2, dashArray = NULL, smoothFactor = 1, noClip = FALSE, popup = NULL, options = pathOptions(), data = getMapData(map))

addRectangles(map, lng1, lat1, lng2, lat2, layerId = NULL, group = NULL, stroke = TRUE, color = "#03F", weight = 5, opacity = 0.5, fill = TRUE, fillColor = color, fillOpacity = 0.2, dashArray = NULL, smoothFactor = 1, noClip = FALSE, popup = NULL, options = pathOptions(), data = getMapData(map))

addPolygons(map, lng = NULL, lat = NULL, layerId = NULL, group = NULL, stroke = TRUE, color = "#03F", weight = 5, opacity = 0.5, fill = TRUE, fillColor = color, fillOpacity = 0.2, dashArray = NULL, smoothFactor = 1, noClip = FALSE, popup = NULL, options = pathOptions(), data = getMapData(map))

addGeoJSON(map, geojson, layerId = NULL, group = NULL, stroke = TRUE, color = "#03F", weight = 5, opacity = 0.5, fill = TRUE, fillColor = color, fillOpacity = 0.2, dashArray = NULL, smoothFactor = 1, noClip = FALSE, options = pathOptions())

addTopoJSON(map, topojson, layerId = NULL, group = NULL, stroke = TRUE, color = "#03F", weight = 5, opacity = 0.5, fill = TRUE, fillColor = color, fillOpacity = 0.2, dashArray = NULL, smoothFactor = 1, noClip = FALSE, options = pathOptions())

Arguments
map
a map widget object created from leaflet()
html
the content of the control. May be provided as string or as HTML generated with Shiny/htmltools tags
position
position of control: 'topleft', 'topright', 'bottomleft', or 'bottomright'
layerId
the layer id
className
extra CSS classes to append to the control, space separated
data
the data object from which the argument values are derived; by default, it is the data object provided to leaflet() initially, but can be overridden
urlTemplate
a character string as the URL template
attribution
the attribution text of the tile layer (HTML)
group
the name of the group the newly created layers should belong to (for clearGroup and addLayersControl purposes). Human-friendly group names are pe
options
a list of extra options for tile layers, popups, paths (circles, rectangles, polygons, ...), or other map elements
baseUrl
a base URL of the WMS service
layers
comma-separated list of WMS layers to show
lng
a numeric vector of longitudes, or a one-sided formula of the form ~x where x is a variable in data; by default (if not explicitly provided), it will be automatically inferred from data by looking for a
lat
a vector of latitudes or a formula (similar to the lng argument; the names lat and latitude are used when guessing the latitude column from data)
popup
a character vector of the HTML content for the popups (you are recommended to escape the text using htmlEscape() for security reasons)
icon
the icon(s) for markers; an icon is represented by an R list of the form list(iconUrl = '?', iconSize = c(x, y)), and you can use icons() to create multiple icons; note when you use an R list tha
clusterOptions
if not NULL, markers will be clustered using https://github.com/Leaflet/Leaflet.markercluster{Leaflet.markercluster}; you can use markerClusterOptions() to specify ma
clusterId
the id for the marker cluster layer
radius
a numeric vector of radii for the circles; it can also be a one-sided formula, in which case the radius values are derived from the data (units in meters for circles, and pixels for circle markers)
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 https://developer.mozilla.org/en/SVG/Attribute/stroke-dasharray{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
lng1, lat1, lng2, lat2
latitudes and longitudes of the south-west and north-east corners of rectangles
geojson
a GeoJSON list, or character vector of length 1
topojson
a TopoJSON list, or character vector of length 1
