fp_scale: Retrieve the scale of a factor

In adas.utils: Design of Experiments and Factorial Plans Utilities

Retrieve the scale of a factor

Description

This is a utility function mostly for internal use.

Usage

fp_scale(fp, fct)

Arguments

fp	The factorial plan object
fct	The standard name of the factor as a string (e.g. "A", or "B", etc.)

Value

A vector representing the factor range in scaled units; scales must have been added with fp_add_scale. If scales are not available, the range in coded units is returned (i.e. c(-1,1))

fp_add_scale()

Examples

df <- fp_design_matrix(2) %>%
  fp_add_names(A="Temperature", B="Pressure") %>%
  fp_add_scale(A=c(20,30), B=c(3, 7))
fp_scale(df, "A")
