mapAttributeOverRaster: Visualize point vector attributes on top of a raster layer

In environmentalinformatics-marburg/magicVis: Smorgasboard for visualization functions

Description

The function plots a raster map as background for a point vector layer.

Usage

mapAttributeOverRaster(raster, vector, attr = 1, vector_colors = "default",
  gnbr = 5, glns = FALSE)

Arguments

raster	a raster layer
vector	a spatial point data frame
attr	column number of the attribute to be visualized
vector_colors	a color palette for the vector layer
gnbr	number of map grid lines (horizontal = vertical)
glns	draw grid lines (TRUE) or just tics (FALSE)

Value

map-type lattice plot object

Examples

library(raster)
library(sp)
data(meuse.grid)
coordinates(meuse.grid) = ~x+y
gridded(meuse.grid) = TRUE
rst <- raster(meuse.grid[3])

data(meuse)
coordinates(meuse) = ~x+y
vec <- meuse[5]

mapAttributeOverRaster(rst, vec, attr = 1)
