R help - Sep 2005 - how to fit the partial association model with R?

If I do not make a mistake,the partial association model is an 
extension of log-linear model.I read a papers which gives an example 
of it.(Sloane and Morgan,1996,An Introduction to Categorical Data 
Analysis,Annual Review of Sociology.22:351-375) Can R fit such partial 
association model?

ps:Another somewhat off-topic question.What's the motivations to use 
log-linear model?Or why use log-linear model?I learn the log-linear 
model butI still do not master the the advantage of the model.thank 
you!

You might like to read the manual at http://math.cl.uh.edu/thompsonla/
under  "An S Manual to Accompany Agresti's Categorical Data Analysis
2nd ed.
(2002)" along with Agresti's book itself.
