Hi, I am trying to predict the habitat suitability of lobster with GAMs. I need to produce a map in ArcGis of the predicted densities. I did some search and the function predict.gam seems to do the job.
Is this the right way to do it? when you apply the function you get the predicted values (different from your input data points) but I do not understand what is the procedure with the spatial coordinates, I mean what lat and long have the new points? Can I use the same ones of my observations? Thank you very much for your time, Valentina Dr. Valentina Lauria Postdoctoral researcher Room 118, Martin Ryan Institute Department of Earth and Ocean Sciences National University of Ireland, Galway Ireland www.nephrops.eu<http://www.nephrops.eu> [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
