Hi,
It appears that there is no package for estimating log linear models (L.
Goodman's family) for data in the form of frequency tables. Am I wrong?
Thanks

Am I wrong?Well, there is no package, but there is inbuilt functionality. Look at loglin, and Bill Venables' formula-driven interface to it, loglm in package MASS. I'm not sure what exactly you are attributing to Goodman, but loglin does the conventional analysis that I thought well predates his work. Plackett attributes it to Birch (1963). -- Brian D.

>It appears that there is no package for estimating log linear models (L. >Goodman's family) for data in the form of frequency tables. Am I wrong?Yes. (Although I don't know Goodman's family.) You can estimate them with family=poisson. See http://www.psych.upenn.edu/~baron/rpsych.htm#tth_sEc6.10 for an example. Also see Venables and Ripley's book, sect. 7.3.
