I fitted a GAM model with Poisson distribution
using the function gam() in the mgcv package.
My model is of the form:
mod-gam(y~s(x0)+s(x1)+s(x2),family=poisson).
To extract estimates at a specified set of covariate
values I used the gam `predict' method.
But I want to get

Gabor,
can you say this in some other way. I appologize, but I just don't
understand anything. I really don't see any connection with R CMD CHECK
and vignettes.
I would just like to see that Sweave would follow \input of \include
commands of LaTeX. You can try with the following example bellow.

Of course: time zone vs. GMT.
Next question: Might a simple example that illustrates this be
added to the help file for as.POSIXct, and if yes, what should be done
to make that happen?
Thanks.

It depends on what you mean by that. Consider the following two
examples:
sum((1:5)==(5:1))
[1] 1
sum((2:1) %in%(1:6))
[1] 2
Does one of these solve your problem?

The above should be:

They happen to be the same by coincidence only, given the values that I

The first syntax returns the _indices_ of the matches, not the actual

I need an advice in the following problem.
I have to maximize two functions of the form f1(x)=f(y1,x,alpha1,beta1) and
f2(x)=(y2,x,alpha2,beta2), the maximization is with respect to alpha1, alpha2,
beta1, beta2. I can maximize each function separately using nlm.
The problem is that
