polySieveM: prepare X matrix with flexible interactions and polynomials

In apoorvalal/LalRUtils: Lal's utility scripts for personal use

prepare X matrix with flexible interactions and polynomials

Description

Prepare matrix with polynomial basis expansion and/or interactions.

Usage

polySieveM(
  dat,
  dummies = NULL,
  continuouses = NULL,
  corr_cut = 0.9,
  k = 2,
  m = 2,
  raw = TRUE
)

Arguments

dat	data table / dataframe
dummies	Names of dummy vars (null by default - auto-detected)
continuouses	Names of continuous vars to modify fn form (null by default - auto detected)
corr_cut	cutoff for correlation threshold to drop one of the vars (default = 0.9)
k	order of interactions: defaults to pairwise interactions
m	order of functions: defaults to quadratic functions
raw	raw or orthogonal bases

Value

data.frame with base terms and interactions + basis
