Description

a method of displaying a Minimum Spanning Tree/Network over a given set of points

Usage

mstlines(mst, x, y = NULL, pts.names = NULL, ...)

Arguments

mst	a minimum spanning tree or network object
x	either a table with the first two columns that of the x and y coordinates respectively, or simply that of the x coordinate
y	an optional argument if the y coordinates were not given in argument x
pts.names	If there is more than one shortest possible branch, should one be chosen randomly
