W-NOMINATE Summary Plot

Description

plot.nomObject reads a W-NOMINATE object in two user-specified dimensions and plots the coordinates, cutting lines, a Coombs mesh, and a Skree plot. For 1-dimensional W-NOMINATE objects, it plots the coordinates against the ranks along with a Skree plot.

Usage
