dat2poly: Create n-degree polynomial from data frame

In egenn/rtemis: Machine Learning and Visualization

Create n-degree polynomial from data frame

Description

This is a convenience function that will take each column of the input and calculate 1:degree powers and concatenate into a data.frame of dimensions n * (degree * p) given an n * p input

Usage

dat2poly(
  dat,
  method = c("simple", "poly"),
  degree = 2,
  raw = FALSE,
  as.data.frame = TRUE
)

Arguments

dat	Numeric, matrix / data.frame: Input
method	Character: "simple", "poly". "simple": raise each column of dat up to degree. "poly": use stats::poly with arguments degree and raw
degree	Integer: degree of polynomials to create. Default = 2
raw	Logical: If TRUE, create simple polynomial, not orthogonalized. Default = FALSE
as.data.frame	Logical: If TRUE, return data.frame. Default = TRUE
