the new map object
a map widget object created from leaflet()
the content of the control. May be provided as string or as HTML generated with Shiny/htmltools tags
position of control: "topleft", "topright", "bottomleft", or "bottomright"
the layer id
extra CSS classes to append to the control, space separated
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
a character string as the URL template
the attribution text of the tile layer (HTML)
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.
a list of extra options for tile layers, popups, paths (circles, rectangles, polygons, ...), or other map elements
a base URL of the WMS service
comma-separated list of WMS layers to show
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)
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)
a character vector of the HTML content for the popups (you are
recommended to escape the text using htmlEscape()
for security reasons)
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
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
A Vector of popupOptions to provide popups
a character vector of the HTML content for the labels
A Vector of labelOptions to provide label
options for each label. Default NULL
if not NULL, markers will be clustered using
Leaflet.markercluster;
you can use markerClusterOptions() to specify marker cluster
options
the id for the marker cluster layer
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)
whether to draw stroke along the path (e.g. the borders of polygons or circles)
stroke color
stroke width in pixels
stroke opacity (or layer opacity for tile layers)
whether to fill the path with color (e.g. filling on polygons or circles)
fill color
fill opacity
a string that defines the stroke dash pattern
Whether the shape should be brought to front on hover.
whether the shape should be sent to back on mouse out.
Options for highlighting the shape on mouse over.
how much to simplify the polyline on each zoom level (more means better performance and less accurate representation)
whether to disable polyline clipping
latitudes and longitudes of the south-west and north-east corners of rectangles
a GeoJSON list, or character vector of length 1
a TopoJSON list, or character vector of length 1
