[Biomod-commits] Error projecting models to another area

[Bruno Arantes]

Hi All.

I'm trying to project models built with BIOMOD but I'm getting the following
error:

Error in predict.nnet(object, Proj, type = "raw") : missing values in 'x'

If I set ANN=F in the Projection call, then the error changes to:
Error in if (sum(ProbData) != 0) { :
  missing value where TRUE/FALSE needed

Does anyone know why this is happening and how to fix it? I suspect it could
have something to do with my dataset containing NA values... is there some
way to set na.action?

Here's info on my environment and data:

R version 2.11.1 (2010-05-31) running on Win XP SP3 (32-bit)
BIOMOD 1.1-5 2010-05-04

Command being used for projection:
> Projection(Proj = other.area[,3:11], Proj.name="test", GLM = T, GBM = T,
GAM = T, CTA = T, ANN = T, SRE = T, FDA =T, MARS = T, RF = T, BinRoc=T,
BinKappa=T, BinTSS=T, FiltRoc=F, FiltKappa=F, FiltTSS=F,
repetition.models=F)

Model training seems to have completed successfully, the only warnings that
appeared were:
glm.fit: fitted probabilities numerically 0 or 1 occurred

Let me know if you need more details about these issues.

Thanks.
