stdrange: Standardize or Unstandarize the Column Range

In vdg: Variance Dispersion Graphs and Fraction of Design Space Plots

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.
