Description

This returns a new function which a linear model has an r-squared of 0.

Usage

subtractlm(func, d, n = d * 100)

Arguments

func	A function
d	Number of input dimensions
n	Number of points to use for the linear model

Value

A new function

Examples

subtractlm(ackley, 2)


  f <- function(x) {
    if (is.matrix(x)) x[,1]^2
    else x[1]^2
  }
