neutralLandscapeMap: Produce a neutral landscape using a midpoint displacement algorithm

Description

This is a wrapper for the nlm_mpd function in the NLMR package. The main addition is that it makes sure that the output raster conforms in extent with the input raster x, since nlm_mpd can output a smaller raster.

Usage

neutralLandscapeMap(x, pad = 10L, ...)

Value

A RasterLayer with same extent as x, with randomly generated values.

Arguments

x

A RasterLayer to use as a template.

pad

Integer. Number of cells by which to pad x internally to ensure nlm_mpd produces a raster corresponding to the dimensions of x.

...

Further arguments passed to NLMR::nlm_mpd

  if (require(NLMR)) {
    library(raster)

    if (interactive()) Plot(map1)
