Dear all,
I am trying to reproduce the exemple in the vignette "Using lme4 to fit
Generalized Additive
Mixed Models" with my dataset.
But...
> mod <- amer(pasvig ~ -1 + harvf + tp(dias,by=harvf) + (1 | pac),
data=exemplo)
Erro em if (from == to) rep.int(from, length.out) else as.vector(c(from, :
valor ausente onde TRUE/FALSE necessário
A subset of the dataset is attached.
No clue about what is wrong.
Thanks a lot!
Marilia
