...r at least in the wrong place. I am attaching a pdf (SVM prediction maps) of the resulting map using probabilities obtained using the code described above (page 1) and a map of what the prediction map should look like given spatial autocorrelation in climate predictors (page 2, map generated using openmodeller). Note that the openmodeller map was created with the same input data and same svm algorithm (also using code from libsvm) as the model in R, just run using different software. I don't know why the prediction map of probabilities based on the model is so different from what I would expect...

Dear All, I have a set of environental maps and presence-only points for some species. How can I generate distributions models on R using these presence-only data? What packages and functions can I use to do so? Kind regards, Miltinho Brazil [[alternative HTML version deleted]]
