sample_neighborhoods: Sample Neighborhoods in a Raster*

In petrelharp/landsim: Simulate Populations on Landscapes

Description

Chooses a set of randomly sampled points centered on non-NA cells of the input RasterLayer, and returns a randomly chosen maximal subset of nonoverlapping circles centered at these points.

Usage

sample_neighborhoods(x, n, radius, separation = radius, thin = TRUE)

Arguments

x	The Raster* object.
n	The number of points to sample.
radius	The radius of the neighborhoods.
separation	The minimum distance separating neighborhood centers (if thin is TRUE).
thin	Whether to thin neighborhoods.

Value

A named list containing: centers = a SpatialPoints object of centers neighborhoods = SpatialPolygons object of the circle(s) center.cells = the indices of the cells of the Ratser* object that contain the centers
