[Biomod-commits] Can I use categorical variables in BIOMOD?

[Wilfried Thuiller]

Hi Andreas,
BIOMOD take categorical variables. Some technique do not (e.g. MARS) but they will be atomically excluded from the runs).
Just make sure your variable is seen as categorical:

MyData = as.factor(MyData)

Best

The data consist of : i) a dataset with the species' localities plus continuous bioclimatic variables, ii) a dataset of background points. Nevertheless, one of the variables is categorical and it describes potential vegetation classes. Its values are distinct, ranging from 1 to 14.
