yatesplot()

Usage:
yatesplot(data,[,fullnorm:T] [,letters:word]),
  data real with length a power of 2, word a character scalar of
  letters to label factors



Keywords: analysis, factorial, plots
yatesplot(y) computes the factorial effects for data y from a
two series design stored in standard order.  It then makes a 
half-normal plot of the effects labelling the terms with labels
A, B, AB, C, and so on.

yatesplot(y,fullnorm:T) does the same, except that it normal scores
plot instead of a half-normal plot.

yatesplot(y[,fullnorm:T],letters:word) where word is a character
scalar such as "DEFG" will make the full- or half-normal plot, but
will label the terms with letters taken from the word, for example,
D, E, DE, F, and so on.  The number of letters in the word must
match the number of factors in y.

If there are more than 10 factors, the effects are not labelled.
