I've been marginally curious about this since 2004, and
spent a little time providing the beginnings of a port
which gives the basic facilities of Mark Newman's code
in R. There is a package on the Omegahat repository
via
install.packages("Rcartogram", repos = "http://www.omegahat.org/R";,
type = "source")
( You will first need to have libfftw3 installed. And there is no
Windows build yet. )
Due to very limited time availability, it is currently reasonably
bare-bones, following the interface provided by Mark, but from within R
and providing a predict() method. But there may be problems, and I
haven't had the time to work on creating the map of the US states.
Feedback, changes, enhancements, examples, etc. encouraged.

Nice stuff. Do you know if anyone has ported the cartogram code to R? I
see a question on the list a couple of years ago
https://stat.ethz.ch/pipermail/r-help/2006-May/106501.html
but I don't see a positive answer...
