Internal point of polygon

Description

Find a central internal point of a polygon

Usage

polyintern(P, n = 10, PLOT=FALSE)

Arguments

P Polygon,xy
n grid dimension over polygon, n by n
PLOT logical, TRUE=plot

Details

A grid is laid over the polygo, the internal points are extracted and for each one the shortest distance to te perimeter is determined. Then the point with the largest distance is returned.

Value

x x coordinate of point
y y coordinate of point
