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.
