dgDivgeomap: Diversity-density geographic map.

In xinghuq/HierDmap: Visualizing the geo-biodiversity profiles and the hierarchical structure of biodiversity

Diversity-density geographic map.

Description

The density of biodiversity in geographic map.

Usage

dgDivgeomap(data, x, y, lon = c(-160, 160), lat = c(-60, 70), 
mapsource = "osm", mapcolor = "color", maptype = "satellite", 
point_color = "red", pointalpha = 0.2, 
pointsize, ...)

Arguments

data	A data frame contains the longitute, latitude, and diversities of each location.
x	The longitude of the sampling location
y	The latitude of the sampling location
lon	The range of longitude in a map
lat	The range of latitude in a map
mapsource	The map sources,Google Maps ("google"), OpenStreetMap ("osm"), Stamen Maps ("stamen")
mapcolor	color ("color") or black-and-white ("bw")
maptype	character string providing map theme. options available are "terrain", "terrain-background", "satellite", "roadmap", and "hybrid" (google maps), "terrain", "watercolor", and "toner" (stamen maps), or a positive integer for cloudmade maps (see ?get_cloudmademap)
point_color	The colour of diversity point
pointalpha	The value used to plot the points.
pointsize	The values used to indicate the relative size the points(diversity).
...	passing to ggplot2.

Details

This function plots the diversity and density of the diversity map using "ggmap"and "ggplot2".

Value

A density and diversity geographic map.
