[R-lang] poly () - which type of orth. polynomials is used?

[Laura Herbst]

Hello there,

I have been trying to find out which type of orthogonal polynomial the
poly() function is based on, but I didn't find it in the help pages or
anywhere else.
Does anyone know whether they are Legendre polynomials, or a different type?

(I want to reconstruct curves on the basis of the calculated coefficients.)

Thanks!

Best
Laura
