[Biomod-commits] GAM error

[Maria Guerrina]

Hi all,
we have a problem with bioclimatic variables and GAM.
If we use more 16 variables in GAM, we have error below.
If we use less 16 variables in GAM, we haven't error
If we use more 16 variables excluding GAM, we haven't error.
We extendend memory limits, since at limit of pc (4GB).
Is it possible using GAM model only on pc with more of 4GB memory?

Thank you all
