| Detailed description |
I’m having some problems with two algorithms when I launch the “BIOMOD_Modeling” function in BIOMOD2. ANN and MARS fail every single time and I don’t know why. The strange thing is that I was able to run both of them until two weeks ago. I’m wondering if the new version (3.4.6) has changed something related to these events.
I tried with different dataset: my data (composed by few occurrence points,), random data downloaded by GBIF (composed by hundreds of occurrence points) and also with the “GuloGulo” example. The result was always the same, a failure.
Could someone help me with this problem?!

(p.s: I tried to reinstall the old version of biomod2, but this hasn’t changed the results (i.e. ANN and MARS don’t work anymore also with old version. ;_;
p.p.s: fortunately, I saved the old “.RData” sessions in which ANN and MARS worked properly.)
