Re: [R] Election Maps
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. D.
