Dear R users,
I would like to include soil as predictor in my model and in addition to
climatic variables. 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.
