R: Cioppa's Nearly Orthogonal Latin Hypercube Designs

nolhDesign {DiceDesign} | R Documentation

## Cioppa's Nearly Orthogonal Latin Hypercube Designs

### Description

This function generates a NOLH design of dimension 2 to 29 and normalizes it to the selected range. The design is extracted from Cioppa's `NOLHdesigns` list.

### Usage

    nolhDesign(dimension, range = c(0, 1))

### Arguments

`dimension` | number of input variables
`range` | the scale (min and max) of the inputs. Range (0, 0) and (1, 1) are special cases and call integer ranges (-m, m) and (0, 2m). See the examples

### Value

A list with components:

`n` | the number of lines/experiments
`dimension` | the number of columns/input variables
`design` | the design of experiments

### Author(s)

T.M. Cioppa for the designs. P. Kiener for the R code.

### See Also

Cioppa's list `NOLHdesigns`. Other NOLH and OLH designs: `nolhdrDesign`, `olhDesign`.

### Examples

    ## Classical normalizations
    nolhDesign(8, range = c(1, 1))
    nolhDesign(8, range = c(0, 0))
    nolhDesign(8, range = c(0, 1))
    nolhDesign(8, range = c(-1, 1))

    ## Change the dimnames, adjust to range (-10, 10) and round to 2 digits
    xDRDN(nolhDesign(8), letter = "T", dgts = 2, range = c(-10, 10))
