echelon: Bring an (edit) matrix to reduced row echelon form.

In editrules: Parsing, Applying, and Manipulating Data Cleaning Rules

Bring an (edit) matrix to reduced row echelon form.

Description

If E is a matrix, a matrix in reduced row echelon form is returned. If E is an editmatrix the equality part of E is transformed to reduced row echelon form. For an editset, the numerical part is transformed to reduced row echelon form.

Usage

echelon(E, ...)

## S3 method for class 'editmatrix'
echelon(E, ...)

## S3 method for class 'matrix'
echelon(E, tol = sqrt(.Machine$double.eps), ...)

## S3 method for class 'editset'
echelon(E, ...)

Arguments

E	a matrix or editmatrix
...	options to pass on to further methods.
tol	tolerance that will be used to determine if a coefficient equals zero.
