Dear S+ users,
I met for the first time a strange problem with plot.gam() which I often
use. I want to plot a simple gam (logistic) model with the following data:
> dim(ovlouga)
[1] 4657 35
> summary(ovlouga[, match(c("mort", "tmin"), table=names(ovlouga))])
mort tmin
Min.:0.00000 Min.:13.80
1st Qu.:0.00000 1st Qu.:17.10
Median:0.00000 Median:18.40
Mean:0.01739 Mean:19.02
3rd Qu.:0.00000 3rd Qu.:20.80
Max.:1.00000 Max.:25.50
> test <- gam(mort ~ lo(tmin, 1/3), data=ovlouga, family=binomial(logit))
> plot.gam(test)
Error: Expressions nested beyond limit (256) -- increase limit with
options(expressions=...)
only 30 of 213 frames dumped
Dumped
There is no problem with the fitted model, and the increase of
options(expression=n) up to 4096 does not change anything.
Did anyone meet the same problem ? How to fix it ?
I am working with S-Plus 4.5 / Win95.
Thanks and best regards,
Renaud
