Create (partial) factorial design
doe(factors, int = "", trials = NA, seed = NA)
| factors | Categorical variables used as input for design |
|---|---|
| int | Vector of interaction terms to consider when generating design |
| trials | Number of trials to create. If NA then all feasible designs will be considered until a design with perfect D-efficiency is found |
| seed | Random seed to use as the starting point |
A list with all variables defined in the function as an object of class doe
