I am wondering if there is any function or command that could generate a
equation automatically from the fitted results?
For example,
> x<-seq(1:20)
> y<-rnorm(20)
> z<-lm(y~poly(x,4))
> z
Call:
lm(formula = y ~ poly(x, 4))
Coefficients:
(Intercept) poly(x, 4)1 poly(x, 4)2 poly(x, 4)3 poly(x, 4)4
0.00557 1.71296 0.55448 -0.10773 -1.45126
Is there any way that I can directly get the equation between y and x for
the fitted curve? Thank you.
