R Documentation

Standardize or Unstandarize the Column Range

Description

Simple functions for rescaling a data matrix to a coded design and back. stdrange converts the design in actual measurements into a coded design, while ustdrange reverses the process (if the correct arguments are given).

Usage

stdrange(x, mins = apply(x, 2, min), maxs = apply(x, 2, max))

ustdrange(x, mins, maxs)

Arguments

`x`	matrix containing the design, or an object coercible to a matrix.
`mins`	vector of original values, one for each column, which should be recoded to the value -1; or which have alreadty been recoded to -1. This and the next argument are both recycled if not of the correct length.
`maxs`	vector of original values which should be recoded as 1, or which have already been recoded to 1.
