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 Luc?a _____________________________________________ Lucia Zarauz AZTI - Tecnalia / Unidad de Investigaci?n Marina Herrera kaia portualdea z/g 20110 Pasaia (Gipuzkoa) Tel: 943 004 800 - Fax: 943 004 801 e-mail: lzarauz at pas.azti.es www.azti.es ; www.tecnalia.info _____________________________________________ ? **************** LEGE OHARRA **************** AVISO LEGAL **************** DISCLAIMER **************** Mezu hau pertsonala eta isilpekoa da eta baimenik gabeko erabilera debekatua dago legalki.
