doff2()

Usage:
doff2(p:fctrs,k:blcks or alout:str or basis:mat [,Ialiases:T]\
       [,allalias:T] [,aber:T] [,showfrac:T] [random:T]) 
	fctrs and blocks positive integer scalars, str the
        output from choosegen2, mat a basis matrix for
	aliasing



Keywords: aliasing, design, factorial
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.
