[Biomod-commits] sample size problem?

[Andreia Mendonça]

Hello all,

I am using BIOMOD to model some data, but I'm facing some errors that i
can't seem to overcome.

As i tried to run the models on some of the populations, the following error
showed up in R:

*Error in nnet.default (x, y, w,...): **initial value in 'vmmin' is not finite


*The error only happens when I try to model populations with 12, 9 or
7 individuals. When i model populations with 40, 26, 19 or even 14
individuals it works just fine.

So this error has to do with the sample size? Is there any way to solve this?

I really appreciate all the help you can give me, since i am much of a
newbie with modelling methods.

*Andreia*
