near.bound {asbio} R Documentation

## 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.
