[Biomod-commits] Question about: Error in if (a != "NA") if (a > 0)

[Ashley Brooks]

Hi,

I am using BioMod version 1.1-3 and R version 2.9.2.  I suppose I should
update these versions?
The following is what I typed into R to run the models and the error message
I recieved.  Also I have listed the summary of my data.  Occurance is just
the name of the column with my 0/1 info on species data.


> Models(GLM = T, TypeGLM = "quad", Test = "AIC", GBM = T, No.trees = 2000,
GAM = T, Spline = 3, CTA = T, CV.tree = 50, ANN = T, CV.ann = 3, SRE = T,
Perc025=F, Perc05 = T, MDA = 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)

Again, I am not sure where to start with troubleshooting.  Any help would be
most appreciated!
