near.bound: Nearest neighbor boundary coordinates

Description

Finds nearest neighbor boundary Cartesian coordinates for use as arguments in function prp.

Usage

near.bound(X, Y, bX, bY)

Value

Returns Cartesian X,Y coordinates of nearest neighbor locations on a boundary.

Arguments

X

A vector of Cartesian X-coordinates (e.g. UTMs) describing an animal's locations (e.g. telemetry data).

Y

A vector of Cartesian Y coordinates (e.g. UTMs) describing an animal's locations (e.g. telemetry data).

bX

A vector of boundary X-coordinates.

bY

A vector of boundary Y-coordinates.
