setMaximumZfromConstant: Initialize maximum allowable z-axis coordinates to a constant...

In mkde: 2D and 3D Movement-Based Kernel Density Estimates (MKDEs)

Initialize maximum allowable z-axis coordinates to a constant value.

Description

Set the upper bounds in the z-dimension for each location in the x and y dimensions to a constant value.

Usage

setMaximumZfromConstant(mkde.obj, val)	

Arguments

mkde.obj	2D or 3D MKDE object created with initialize3DMKDE or initialize3DMKDE, respectively
val	The value at which the upper bound should be set for all locations in the x and y dimensions.

Details

Obviously, the upper bound must be greater than the lower bound.

Value

An updated MKDE list object is returned.

Examples

library(terra)
fpath <- system.file("extdata", "dugongdem.RDS", package="mkde")
dugongdem <- terra::readRDS(fpath)
cell.sz <- mean(res(dugongdem))
ext <- ext(dugongdem)
nx <- ncol(dugongdem)
ny <- nrow(dugongdem)
mkde.obj <- initializeMKDE3D(ext$xmin, cell.sz, nx, ext$ymin, cell.sz,
ny, min(values(dugongdem), na.rm=TRUE), 50.0, 15)
mkde.obj <- setMaximumZfromConstant(mkde.obj, 100.0)
