R: Count Number of Vertices

nvertices {spatstat.geom}

R Documentation

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 class 'owin'
nvertices(x, ...)

  ## Default S3 method:
nvertices(x, ...)

Arguments

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

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)).

Value

A single integer.
