Class planordesign

Description

An S4 class to represent a final design.

Objects from the Class

Objects can be created by calls to method planor.design applied on an object of class designkey or on an object of class listofkeyrings, and by calls to regular.design when argument output is equal to ‘planordesign’.

Slots

design

a dataframe containing the final design.

factors

an object of class designfactors which contains the factors specifications.

model

a list containing the model and estimate specifications.

designkey

a list of the keymatrix objects used to create the object.

nunits

the number of units of the design.

recursive

a logical equal to TRUE if the design has been constructed recursively.

Methods

getDesign

extract a design data frame. See getDesign method.

as.data.frame

coerce into a data frame. See as.data.frame method.

showClass("planordesign")
### Creation of a listofdesignkeys object
K0 <- planor.designkey(factors=c("R","C","U","A","B1","B2"),
 nlevels=c(3,2,2,3,2,2), model=~R*C + (A+B1+B2)^2, estimate=~A:B1+A:B2,
 nunits=12, base=~R+C+U, max.sol=2)
### Creation of a planordesign object from K0
P0 <- planor.design(key=K0, select=1)
show(P0)
