Description

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

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

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)).
