Find linear dependent columns in a design matrix

Description

Find linear dependent columns in a design matrix

Usage

find_linear_dependent_columns(mat, tol = 1e-12)

Arguments

mat	a matrix
tol	a double that specifies the numeric tolerance

Value

a list with vectors containing the indices of linearly dependent columns

The algorithm and function is inspired by the internalEnumLC function in the 'caret' package (GitHub)

Examples

  mat <- matrix(rnorm(3 * 10), nrow = 10, ncol = 3)
  mat <- cbind(mat, mat[,1] + 0.5 * mat[,3])
  find_linear_dependent_columns(mat)  # returns list(c(1,3,4))
