doff2() is a front end combining many of the tasks of aliases2(), choosegen2(), and aberration2(). There are two sorts of arguments: those that determine the design, and those that determine what is printed. All arguments are keyword phrases. To determine the design, you may enter p and k, or alout, or basis. Using p and k says to create a new 2^(k-p) design. The other options use a previously created design, either alout, the output from a previous usage of choosegen2(), or basis, a k by p matrix of 0's and 1's indicating the generators for the design. The phrase random:T means to choose a random fraction from the family determined by the generators. The remaining four arguments determine what is printed: Ialiases:T Print the aliases of I allalias:T Print all aliases aber:T Print the number of confounded effects by word length showfrac:T Print the treatments in the fraction.
