patch: Patches coordinates

Description

Report the coordinates of the patches at the given [x, y] locations.

Usage

patch(world, x, y, duplicate = FALSE, torus = FALSE, out = FALSE)
# S4 method for worldNLR,numeric,numeric
patch(world, x, y, duplicate = FALSE, torus = FALSE, out = FALSE)

Value

Matrix (ncol = 2) with the first column pxcor and the second column pycor representing the patches coordinates at [x, y].

Arguments

world

WorldMatrix or worldArray object.

x

Numeric. Vector of x coordinates. Must be of same length as y.

y

Numeric. Vector of y coordinates. Must be of same length as x.

duplicate

Logical. If more than one location [x, y] fall into the same patch and duplicate == TRUE, the patch coordinates are returned the number of times the locations. If duplicate == FALSE, the patch coordinates are only returned once. Default is duplicate == FALSE.

torus

Logical to determine if the world is wrapped. Default is torus = FALSE.

out

Logical. If out = FALSE, no patch coordinates are returned for patches outside of the world's extent, if out = TRUE, NA are returned. Default is out = FALSE.

Details

If a location [x, y] is outside the world's extent and torus = FALSE and out = FALSE, no patch coordinates are returned; if torus = FALSE and out = TRUE, NA are returned; if torus = TRUE, the patch coordinates from a wrapped world are returned.
