[Biomod-commits] Error in Models

[Wilfried Thuiller]

Dear Ashley,

In the help file you will see that we have changed the call for the SRE models. 
?Models
I am sorry if we have let the old version in the manual or elsewhere. We are updating the manual at the moment.
Biomod.Manual()

That should work: 

I replaced the Perc025 and Perc05 by quant=0.05. This is more flexible as you can select the percentile you want.
MDA is not longer in BIOMOD and has been replaced by FDA

Models(GLM=T, TypeGLM="poly", Test="AIC", GBM=T, No.trees=2000, GAM=T, Spline=3, CTA=T, CV.tree=50, ANN=T, CV.ann=2, SRE=T,quant=0.05, FDA=T, MARS=T, RF=T, NbRunEval=3, DataSplit=70, Yweights=NULL, Roc=T, Optimized.Threshold.Roc=T, Kappa=T, TSS=T, KeepPredIndependent=T, VarImport=5, NbRepPA=2, strategy="circles", coor=Coors, distance=2, nb.absences=1000)

Just a tip: when you have "unused arguments" in an error message, it generally means you have specified some arguments which does not exist in the function (in your case it was Perc025, Perc05 and MDA). Check the function and the help file and try to see where are these arguments you would like to add which do not exist. This is true for all functions in R.

Hope it helps,
Wilfried
