Value

identity in character representation

columns

Methods

signature(x = "facDesign")

Calculates the alias table for a fractional factorial design and prints an easy to read summary of the defining relations such as ‘I = ABCD’ for a standard 2^(4-1) factorial design.

signature(x = "taguchiDesign")

Calculates the alias table for a fractional taguchi design and prints an easy to read summary of the defining relations such as ‘I = ABC’ for a standard “L4_2” taguchi design.

#generate a 2^(4-1) factorial design by assigning the interaction ABC 
#to the factor D
vp = fracDesign(k = 4, gen = "D = ABC")

#the defining relation is (D = ABC)*D = I = ABCD. I is the identity.
identity(vp)

#the identity can be seen in the according alias table
