See my short course, http://www.datavis.ca/courses/VCD/

in particular, http://www.datavis.ca/courses/VCD/R/mental-glm.R

# fit linear x linear (uniform) association.  Use integer scores for 
rows/cols
Cscore <- as.numeric(Mental$ses)
Rscore <- as.numeric(Mental$mental)
linlin <- glm(Freq ~ mental + ses + Rscore:Cscore,
                 family = poisson, data = Mental)
