Class listofkeyrings

Share:

Description

An S4 class to store design key solutions when there is only one prime involved or when the solutions are independent between primes.

Objects from the Class

Objects are created by planor.designkey, when the case is not recursive.

Slots

.Data

a list of objects of class keyring associated with different primes.

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.

Extends

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

Methods

alias

give the aliasing for each key-matrix. See alias method.

[

extract one design key by taking one key matrix per prime.

pick

extract one design key by taking one key matrix per prime. See pick method.

planor.design

build a design using one key matrix per prime. See planor.design method.

show

display the object. See show method.

summary

summarize the design properties from object. See summary method.

   model=~block+(A+B+C+D)^2, estimate=~A+B+C+D,
   nunits=3^3, base=~A+B+C, max.sol=2)
