[R] plotting gam models

[Lucia Zarauz]

Hi everybody,

I am working with gams and I have found some questions when plotting gams models.

I am using mgcv, and my model looks something like this:

model<- gam(x ~ s(lat,long))

I can plot the output of the model using plot(model) or plot.gam(model) and I get a surface plot. 

That is ok, but what I want to do now is to extract the data used to perform the surface plot. Like that I would be able to superpose them to a geographical map, and to plot these data using other programs.

Thank you very much in advance

Lucía
