Have you look at zelig (http://gking.harvard.edu/zelig/) ? It unifies a lot of statistical models within a framework that describes variable types for input and output. You might also try searching for "statistical expert systems" - e.g. More Intelligent Statistical Software and Statistical Expert Systems: Future Directions. Gerald J. Hahn. The American Statistician, Vol. 39, No. 1 (Feb., 1985), pp. 1-8.
