Soil as predictor in SDM
Hi, This is addressed briefly in section 4.2 of the dismo package vignette. https://cran.r-project.org/web/packages/dismo/vignettes/sdm.pdf <https://cran.r-project.org/web/packages/dismo/vignettes/sdm.pdf> Does that answer your question? Ben

Anyway I have some doubts concerning the usd of categorical values such as the format of my raster file. Actually, my soil type data are categorical codes, should these codes be described as categories prior to be used? Or shoul I reclassify my raster into numeric values? My main concern is if I would create directional influence and bias in the results. Thanks -- Maurizio Marchi Skype ID: maurizioxyz linux user 552742 [[alternative HTML version deleted]]
