Thanks Simon, by cloning a smooth construct do you mean copying and
modifying the smooth constructor code? Could you pleas elaborate on
your answer? Which is the Predict.matrix method?

There probably is a way, but it involves some programming. You would
need to clone a smooth constructor (e.g. for the "cr" class), and then
modify it to add a linear constraint matrix C to the returned smooth
object. If b are the smooth coefficients then C should be the matrix
such that s(0) =
I am fitting a model in which the response variable y is a function of
two independent, quantitative variables x1 and x2; thus: y = f(x1,
x2). For reasons I do not believe to be important for the purpose of
this post, I find it desirable to find f by means of GAM; also, I
require principal effects
