Zelig

Looking up some information on ordinal logit models in R today, I came across Zelig. Produced by Kosuke Imai, Gary King, and Olivia Lau, Zelig is a sort of R meta-package that wraps, for example, various fuctions of the MASS or VGAM libraries into a smaller set of commands. The authors subtitled Zelig “Everyone’s Statistical Software,” with the idea that it will make R more accessible while not cutting off any of its power. Zelig appears to be a couple of years old now, but I hadn’t run into it before; maybe I’m hanging around on the wrong mailing lists?
