Re: [R] Create a function automatically from lm formula and coefficients?

Hi, I need to create a function from lm formula and coefficients to use it in my c++ code later. but when I do it as you said require(rms) f - ols( ) g - Function(f) g(x1=2,x2=3,...) I realize that it didn't give me the same result as predict.lm? how can I reach a function to give me the same

[R] Create a function automatically from lm formula and coefficients?

I hope the subject says it all. I want to be able to use an lm object and the associated coefficients to create function that can produce expected y values given inputs. Thanks, KW -- [[alternative HTML version deleted]] __
