Hi Arnaud,
your question has in fact nothing to do with gam or model selection.
What you are asking is: what is the logical expression that yields True
when AB is False or both A and B are True. Now replace the words with
operators (!AB | (A B)) and voilà.

Hello R-list
Maybe someone knows what's going on here.

Please use plan text. HTML is not handled correctly.
Within your last statement it appears you are trying to find the sum of a
logical vector - is.na(). This is what is causing the error.
My guess is that you want to count the number of elements in the second column
that are not NA

That is false:

I have used loess() for this purpose primarily to take advantage of
