planor (version 1.5-3)

designkey-class: Class designkey

Description

An S4 class to represent a design-key solution.

Objects from the Class

Objects can be created by extraction from an object of class '>listofkeyrings or class '>listofdesignkeys.

Slots

.Data

a single design-key solution, i.e a list with one '>keymatrix per prime.

factors

an object of class '>designfactors which contains the factors specifications.

model

a list which contains the model and estimate specifications.

nunits

the number of units of the design.

recursive

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

Extends

Class '>list, from data part. Class '>vector, by class list, distance 2.
