ctmcmove (version 1.2.1)

get.crawl.path: Simulate a CRAWL path within a raster object.

Description

This function simulates a quasi-continuous CRAWL path that does not leave the borders of a raster object. Output includes the crawl xyt locations and the discretized path on the raster grid.

Usage

get.crawl.path(sim.obj, raster, mintime, maxtime, ...)

Arguments

sim.obj

A CRAWL sim.obj.

raster

A raster or raster stack object. The simulated CRAWL path will be required to stay within the confines of the raster object.

mintime

Time to begin simulating the CRAWL path.

maxtime

Time to end simulating the CRAWL path.

...

Legacy. Not used.

Value

• t
  A vector of times at which the CTCRW path is sampled
• xy
  A 2-column matrix of xy locations of the CTCRW path
• cells.path
  A vector of the raster cell of the CTCRW location at each time in "t"

Details

This is a wrapper function for CRAWL simulation functions and depends on a valid crawl sim.obj.
