leafloc: Add Leaflet map widget for point location.

In leonawicz/snapplot: Collection of Functions for Graphing SNAP Data Sets

Description

Add a Leaflet map widget centered on a point to a static or interactive document or a Shiny app.

Usage

leafloc(loc, bottom = "Stamen.Watercolor", top = "Stamen.TonerLite",
  width = "100%", op = 0.5, zoom = 12)

Arguments

loc	character or numeric, name of available point location or specific coordinates. See details.
bottom	character, bottom layer provider tile set.
top	character, top layer provider tile set.
width	character, map widget width, defaults to "100%".
op	numeric, opacity for bottom and top tile sets, respectively. If length-1, will be repeated.
zoom	integer, map zoom, defaults to 12.

Details

This function generates a Leaflet map centered on loc where loc is the string name of a point location from the snaplocs package. Alternatively, the function can be used more generally by providing a length-2 vector of longitude and lattitude. This canned map widget uses two provider tile sets, each with default opacity, op = 0.5.

Value

a Leaflet map.

Examples

leafloc("Anchorage")
leafloc(c(0, 52), zoom = 6)
