In planor: Generation of Regular Factorial Designs

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

An S4 class to represent a list of design key solutions.

Objects are created by planor.designkey, when the search is recursive.

.Data: a list of objects of class designkey.
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 in the design.

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

alias: NOT YET IMPLEMENTED.
[: extract one design key in the list.
pick: extract one design key in the list. See pick method.
planor.design: build a design from one design key in the list. See planor.design method.
show: display the object. See show method.
summary: summarize the design properties. See summary method.

### Creation of a listofdesignkeys object
K0 <- planor.designkey(factors=c("R","C","U","A","B1","B2"),
 nlevels=c(3,2,2,3,2,2), model=~R*C + (A+B1+B2)^2, estimate=~A:B1+A:B2,
 nunits=12, base=~R+C+U, max.sol=2)
###  Method show
show(K0)
### Method length
length(K0)
### Extract component. The two following two commands are equivalent 
K <- K0[2]
K <- pick(K0,2)
