designFactorial: Create a Design Matrix for a Factorial Design

Description

The function creates a design matrix suitable for analyzing results from a factorial experiment where all factors have two levels.

Usage

designFactorial(nfactors, replications = 1, interactions = FALSE)

Arguments

nfactors

The number of two-level factors in the experiment.

replications

The number of replications at each combination of factor levels.

interactions

If TRUE, columns will be included representing the interactions between all the factors.

Value

A matrix where the number of rows is \(2^nk\), where \(n\) is the number of factors and \(k\) is the number of replications. The entries are -1's and 1's.
