# Class listofkeyrings

### 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.
