mkde (version 0.1)

mkdeToRaster: MKDE to RasterLayer or RasterStack

Description

Converts an MKDE into a RasterLayer or RasterStack so that raster package functions can be used.

Usage

mkdeToRaster(mkde.obj)

Arguments

mkde.obj

A 2D, 2.5D, or 3D MKDE object created with initialize2DMKDE or initialize3DMKDE and density initialized with initializeDensity

Value

If the MKDE is 2D or 2.5D, a RasterLayer object is returned. If the MKDE is 3D, a RasterStack is returned with one layer in the stack per level.

Details

This method converts the density array in the MKDE oject to an object of a class from the raster package. This allows the functions in the raster package to be used with the MKDEs.

Examples

## Not run: 
# library(raster)
# # set up MKDE object
# data(pandadem)
# cell.sz <- mean(res(pandadem))
# ext <- extent(pandadem)
# nx <- ncol(pandadem)
# ny <- nrow(pandadem)
# mkde.obj <- initializeMKDE2D(ext@xmin, cell.sz, nx, ext@ymin, cell.sz, ny)
# 
# # set up movement data
# data(panda)
# mv.dat <- initializeMovementData(panda$time, panda$x, panda$y, 
# sig2obs=25.0, t.max=185.0)
# 
# # estimate density
# dens.res <- initializeDensity(mkde.obj, mv.dat)
# mkde.obj <- dens.res$mkde.obj
# mv.dat <- dens.res$move.dat
# mkde.rst <- mkdeToRaster(mkde.obj)
# plot(mkde.rst)
