Does anyone know of an R or S-Plus function to draw scaled
rectangle diagrams? This variation on Venn diagrams is described here:
Marshall, RJ. Displaying clinical data relationships
using scaled rectangle diagrams. Statist. Med. 2001;20:1077-1088.
http://www.health.auckland.ac.nz/population-health/epidemiology-biostats/span/sim_rectanglediagrams.pdf
Note to my academic colleagues: Given the algorithmic,
geometric, and graphical issues that Marshall
lays out, it seems to me that this would make a great programming project for
tormenting undergraduates.
