poly

Polynomial basis expansion

Generates a basis of polynomial terms for a numeric vector.

Parameters

• x (Vector[Number]): | List[Number] The vector to expand.

• degree (Int): The degree of the polynomial.

• raw (Bool): = false If true, return raw powers instead of orthogonal polynomials.

Returns

A named list of polynomial terms.

Examples

mutate(df, !!!poly($age, 3, raw = true))
