Hi All,
I am trying to generate a function from a linear model. I think there should be build-in function that perform this action but I've had no luck finding it.
For example, I have a model created using lm().
model <- lm(sat.d~1+sat.n+I(sat.n^2))
What I would like to have is a function (similar to the one generated by splinefun()) so that I can use it on different data-sets.
Thanks in advance for the help.
