Q: Has anyone implemented cartograms [**] in R? A search on the R  
site turned up
	https://stat.ethz.ch/pipermail/r-sig-geo/2005-December/000698.html
which led to
	http://www.okada.jp.org/RWiki/index.php?cmd=read&page=Rmap%A4%F2%BB% 
C8%A4%C3%A4%BF%C3%CF%BF%DE%C9%BD%BC%A8&word=Rmap#content_1_35

which has (one form of) a cartogram as a PNG, but which doesn't seem  
to have code.  (The site is in Japanese, so I can't be sure on the  
code availability.)

** A cartogram are geographical maps in which region boundaries are  
distorted to represent some property of interest, e.g. population  
density.  For an introduction, see
	http://en.wikipedia.org/wiki/Cartogram
and for some elegant examples for election results, see
