factDesign: Full Factorial Designs

In DiceDesign: Designs of Computer Experiments

Description

Create a factorial design with n = pow(levels,dimension) experiments in [0,1]^d.

Usage

factDesign(dimension, levels)

Arguments

dimension	an integer given the number of input variables
levels	an integer given the number of levels

Details

It is possible to take a different number of levels for any factor. In this case, the argument levels should be a vector.

Value

factDesign returns a list containing all the input arguments detailed before, plus the following components:

n	the number of experiments
design	the design of experiments

Examples

## First example
g1 <- factDesign(2, 7)
plot(g1$design, xlim=c(0,1), ylim=c(0,1))

## Second example
g2 <- factDesign(2, c(2,7))
plot(g2$design, xlim=c(0,1), ylim=c(0,1))

## Change the dimnames, adjust to range (-10, 10) and round to 2 digits
xDRDN(g1, letter = "T", dgts = 2, range = c(-10, 10))
xDRDN(g2, letter = "T", dgts = 2, range = c(-10, 10))
