Hi Wilfried,

Thanks so much for the help. I did manage to fix the Projection
problem I was having(now I have a new projection problem)

And now I am also having problems with the actual
Ensemble Forecasting. This is the error I am getting:

Ensemble.Forecasting(Proj.name= "area", weight.method='Roc', PCA.median=T,
+ binary=T, bin.method='Roc', Test=F, decay=1.6, repetition.models=T)
Sp1
Error in rep(1, sum(wk != 0)) : invalid 'times' argument

Is it because GBM is included again when it says repetition.models=T?

I tried putting only the ones that are tru, but I got errors for that as well.

What does the line mean - Error in rep(1, sum(wk != 0)) : invalid
'times' argument?

Thanks again for any help.

Best wishes,
Samiya
