If an interaction term is used in a gam, the plot of the interaction
term can at times obscure interesing information. If plot.gam() could
be persuaded to do a contour plot instead, I could see what's
happening over the other side of the hill. I can't make head nor tail
out of the code for plot.gam. What part is recognising factors?
Thanks for suggestions.
Patrick
