[R] modeling interaction of continuous vars

Dear R-Users,

I wonder what methods are available for modeling interaction of continuous
variables. Specifically I am interested in fitting a regression

y ~ f(w) * x

where y, x are vectors and f(w) is a smooth function of a continuous
parameter w (so it is f() that needs to be estimated). I can further assume
that f(w) is positive but I can not take the logarithms as both y and x can
be negative.

Thanks, Vadim
