In jspijker/dgsa: Dutch Geochemical Soil Atlas, Data and Functions.

Description

Create a spatial bubble map

Usage

map(x)

Arguments

x	name of the element

Details

A bubble map is a simple way to both show spatial distribution and magnitude of measurements. It shows the data without an underlying interpolation model like inverse distance and kriging.

In ths implementation ggplot2 is used to draw the map and the bubbles (circles). Usually, a specific function is chosen to relate the magnitude of the measurement to the size of the bubble, using radius or area. The map function uses the size argument in the aes function.

Examples

p <- map("xrfal2o3")
print(p)
