3-D Plotting of predictions from GAM/GAMM object
...on is: How can I create an appropriate matrix of values from a GAM (actually a GAMM) to make a 3-D plot? This model is fit as a tensor product spline of two predictors and I have used it to make specific predictions by calling: YoyRasPred6<-predict(YoyRas.Distribution.T.L.DT.gamm$gam,newdata=YoyRasSubset6,se.fit=T) However, this type of command, I believe, produces only a vector of values. I have plotted these values and know how to do so in 2-D. However, I would like to create a 3-D plot, which I believe will require an entire matrix of predictions (z values) based on all possible inputs (x an...
