[Biomod-commits] Error in model.frame.default - "invalid type (list) for variable" - using BIOMOD

[Oscar Javier Ramos]

Hi,

I'm beginning with BIOMOD.

Just running the example on the "BIOMOD: Tutorial (February 13, 2012)" =>
data(Sp.Env)",

I got the following error:

Number of species modelled :            2
Sp281, Sp290

numerical variables :                   Var1, Var2


number of evaluation repetitions :      3

         2 Fold Cross Validation + 3 Repetitions
Calibration and evaluation phase: Nb of cross-validations:  3

Error in model.frame.default(formula = eval(parse(text =
paste("Target[Samp$calibration]",  :
  invalid type (list) for variable 'Var1'


Could anyone help me to overcome this problem?


Thanks,

Oscar
