planor (version 1.5-3)

keymatrix-class: Class keymatrix

Description

An S4 class to represent an elementary key matrix.

Objects from the Class

Objects from this class are usually components of an object of class '>keyring or '>designkey.

Slots

.Data

a matrix of integers modulo p.

p

a prime number.

Extends

Class '>matrix, from data part. Class '>array, by class matrix, distance 2. Class '>structure, by class matrix, distance 3. Class '>vector, by class matrix, distance 4, with explicit coerce.

Methods

alias

give the aliasing relationships of the key matrix. See alias methods.

show

display the object. See show methods.

summary

summarize the design properties. See summary methods.

Examples

# NOT RUN {
showClass("keymatrix")
### Creation of a listofkeyrings object
K0 <- planor.designkey(factors=c("block", LETTERS[1:4]), nlevels=rep(3,5),
    model=~block + (A+B+C+D)^2, estimate=~A+B+C+D,
    nunits=3^3, base=~A+B+C, max.sol=2)
### Show a keymatrix of K0
show(K0[[1]][[1]])
