In dschlaep/ecotoner: ecotoner - ecotones / ecological boundaries across environmental gradients

Description

Locate candidate transect lines of (sufficient) homogeneous aspect THAs

Usage

locate_candidate_THAs(n, grid_gradient, max_neighborhood, asp201Mean, asp201SD,
  abuts, max_aspect_sd, max_aspect_diff, width_N, seed = NULL)

Arguments

n	An integer. The size of initial random sample of starting points to locate candidate transect lines within areas of abut and where asp201SD <= max_aspect_sd.
grid_gradient	A RasterLayer object representing the environmental gradient, e.g., elevation.
asp201Mean	A RasterLayer object.
asp201SD	A RasterLayer object.
abuts	A RasterLayer object.
max_aspect_sd	A numeric. Limits the search area for line-starting points to where asp201SD <= max_aspect_sd.
max_aspect_diff	A numeric. Cuts the candidate lines to areas where asp201Mean differs from the mean aspect at the starting point differs by less than max_aspect_diff.
width_N	An integer. The width of the band transect in number of grid cells which will be put around the transect line.
seed	An integer value, NA, or NULL to set the random number generator. NULL follows the behavior of set.seed.
