In planor: Generation of Regular Factorial Designs

Description Objects from the Class Slots Extends Methods Author(s) See Also Examples

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

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

.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.

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

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.

### Creation of a listofkeyrings object

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