[Biomod-commits] ANN and VarImportance

[Cris Cris]

When I include the presence-absence of a host specie as a variable, the VarImportance of ANN shows only zeros associated with the host layer. 
All other algorithms show the opposite: the host is the most important variable.
All the rest is ok: I can plot the ANN's results and reach some good values of AUC but this result of VarImportance seems strange. 
Thank you for the support.
