Dear all,
   
  I fitted a non-parametric model using GAM function in R. i.e., 
  gam(y~s(x1)+s(x2))  #where s() is the smooth function 
  Then I obtained the coefficients(a and b) for the non-parametric terms. i.e.,
  y=a*s(x1)+b*s(x2)
   
  Now if I want to use this estimated model to do optimization or sensitivity analysis, I am not sure how to incorporate the smooth function since s() may not be recognized outside GAM environment.
   
  Thank you in advance!
