Dear R help,
I am fitting a gam model with package GAM ( I use lo() to fit
2 non-parametric
additive components).
When I plot the GAM object, along with the graphics window
displaying plots of
each components, I read the following warnings at the prompt:
3: the condition has length 1 and only the first element will
be used in: if
(scale2 < scale) rep(mean(ylim), 2) + ((ylim - mean(ylim)) *
4: number of items to replace is not a multiple of
replacement length .
I am changing the scale parameter but I still get the same warnings.
I have no idea of the meaning of the warnings, I would be
grateful if you could
help.
Is it possible to find a C code of th ebackfitting algorithm?
Many thanks,
Chiara
