I've been told that you may be able to help.

I have a complex linear model with multiple two-way interaction terms. Is
there a way to view the interaction terms in a 3d plot equivalent to the S
> plan<-interp(x,y,z)
> image(plan)

where x and y are my explanatory variables and z my response variable.
