[R] polynomial regression and poly

[Robert.Denham@dnr.qld.gov.au]

When doing polynomial regression I believe it is a good idea to use the poly
function to generate orthogonal polynomials.  When doing this in Splus there
is a handy function (transform.poly I think) to convert the coefficients
produced by regression with the poly function back to the original scale.
Has somebody written something similar for R ?
