nvertices: Count Number of Vertices

Description

Count the number of vertices in an object for which vertices are well-defined.

Usage

nvertices(x, …)
  # S3 method for owin
nvertices(x, …)
  # S3 method for default
nvertices(x, …)

Arguments

x

A window (object of class "owin"), or some other object which has vertices.

…

Currently ignored.

Value

A single integer.

Details

This function counts the number of vertices of x as they would be returned by vertices(x). It is more efficient than executing npoints(vertices(x)).
