safi (version 1.0)

createSafiDesign: Creating an initial DoE for a given number of (functional) inputs

Description

An initial design object is created.

Usage

createSafiDesign(method = "SB", mirrored.runs.included = FALSE, d.f = 1, variable.names)

Arguments

method

a character string specifying the evaluation method to be chose from "SB" and "other". Currently only "SB", sequential bifurcation, is implemented. For "other" the DoE has to be added to the object manually.

mirrored.runs.included

boolean. If TRUE mirror runs will be included in the design.

d.f

number of (functional) inputs

variable.names

optional variable names (if NULL names are set to x1,x2,...)

Value

safidesign object containing DoE, split.points and d.f, mirrored.runs.included and method
