Mapping Public Opinion: A Tutorial

At the upcoming 2012 summer meeting of the Society of Political Methodology, I will be presenting a poster on Isarithmic Maps of Public Opinion. Since last posting on the topic, I have made major improvements to the code and robustness of the modeling approach, and written a tutorial that illustrates the production of such maps.

This tutorial is in a very rough draft form, but I will post it here when it is finalized. (An earlier draft had some errors, and so I have taken it down.)

    David, I have been following your work since I found your maps through a link. Congratulations on being linked at R-Bloggers. Can you write some posts on how you are using Bayesian probability in your research.

    Hi David,
    I have the data in which I have classified the US states in 3 classes. I want to color the state according to the class. Please help doing this.

    I have done the similar exercise for countries usin “rworldmap”, but not able to do this for the US states.
    Please help.

    Many thanks.
