What is Orthogonal Polynomials in R Documentation about?

This document discusses orthogonal polynomials in R. It shows how to generate orthogonal polynomial contrasts using contr.poly for different values of k, and how the contrasts are normalized by dividing each by the square root of the length. It also demonstrates customizing the calculation using a user-defined function and applying it to different values of k.
