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 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. |
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 column named lng, long, or longitude(case-insensitively) |
lat | a vector of latitudes or a formula (similar to the lngargument; 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 useicons() to create multiple icons; note when you use an R list that contains images as local files, these local image files will be base64 encoded into the HTML page so the icon images will still be available even when you publish the map elsewhere |
popupOptions | A Vector of popupOptions to provide popups |
label | a character vector of the HTML content for the labels |
labelOptions | A Vector of labelOptions to provide label options for each label. Default NULL |
clusterOptions | if not NULL, markers will be clustered usingLeaflet.markercluster; you can use markerClusterOptions() to specify marker cluster options |
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 thedata (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 strokedash pattern |
bringToFront | Whether the shape should be brought to front on hover. |
sendToBack | whether the shape should be sent to back on mouse out. |
highlightOptions | Options for highlighting the shape on mouse over. |
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 |
Value

object
