near.bound {asbio}

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)

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.

Value

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