[R] cartograms in R?

[Dan Kelley]

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

and for some elegant examples for election results, see
