lmap: Create an interactive map

In s-u/rcleaflet: Interactive maps in RCloud based on the Leaflet package

Description

lmap creates an instance of an interactive map using Leaflet.

Usage

lmap(x = NULL, y = NULL, zoom = NULL, where, xlim = NULL, 
    ylim = NULL, width = 800, height = 600,
    tilepath = "https://rcloud.research.att.com/tiles-light/{z}/{x}/{y}.png", 
    eventfunc = NULL, lat = y, lon = x)

Arguments

x	convenience positional shortcut for lon
y	convenience positional shortcut for lat
zoom	zoom level
lat	latitude of the center or points to base the center on
lon	longitude of the center or points to base the center on
where	optional, string identifying the element which will contain the map using jQuery selector notation. If absent, a new <div> element is created using rcloud.html.out.
width	if where is missing, the width (in pixels) of the new map element
height	if where is missing, the height (in pixels) of the new map element
xlim	range of longitudes to show
ylim	range of latitudes to show
tilepath	specification for tiles URLs
eventfunc	named list of callback functions to register

Details

lmap creates a new instance of a Leaflet intercative map. It also sets the current active map to this objects such that calls to lpoints and other plotting functions will default to this instance if no map is specified explicitly.

Callback functions should generally have the signature function(i, ...) where i is the index of the element that triggered the callback (for lpoints, lmarkers etc). For lmap it is always 0.

Value

Returns an object of the class RCloudLeaflet representing the map.
