[Biomod-commits] GAM error return

[Hakim Abdi]

Dear All:

I'm getting the following error when loading the GAM model:

> load("models/SPECIES1_GAM_full")
> SPECIES1_GAM_full

Family: binomial
Link function: logit

Formula:
SPECIES1 ~ s(BAND5, 3) + s(BAND7, 3)

Estimated degrees of freedom:
Error in x$smooth[[i]]$first.para :
  $ operator is invalid for atomic vectors

> summary(SPECIES1_GAM_full)
NULL
Formula:
NULL

Error in if (x$m > 0) { : argument is of length zero

While the GLM model returns the following:

> load("models/SPECIES1_GLM_full")
> SPECIES1_GLM_full

Call:  glm(formula = SPECIES1 ~ I(BAND7^3) + BAND4 + I(BAND5^2), family =
binomial,      data = DataBIOMOD[calib.lines, ], weights =
Yweights[calib.lines,          i])

Coefficients:
(Intercept)   I(BAND7^3)        BAND4   I(BAND5^2)
 -6.566e-01   -3.090e-06   -1.373e-02    1.527e-04

Degrees of Freedom: 342 Total (i.e. Null);  339 Residual
Null Deviance:      467.3
Residual Deviance: 428.4        AIC: 436.4

My model setup parameters are as follows:

> Models(GLM = T, TypeGLM = "quad", Test = "AIC", GBM = F, No.trees = 3000,
GAM = T, CTA = F, CV.tree = 50, ANN = F, CV.ann = 2, SRE = F, Perc025=T,
Perc05=F, MDA = F, MARS = F, RF = F, NbRunEval = 2, DataSplit = 80,
Yweights=NULL, Roc=T, Optimized.Threshold.Roc=T, Kappa=T, TSS=T,
KeepPredIndependent = F, VarImport=5, NbRepPA=0, strategy="circles",
coor=CoorXY, distance=2, nb.absences=1000)

Am I missing something?

Thanks in advance for the assistance.
