R help - Nov 1999 - Yates analysis

Dear all:

I need to perform a Yates analysis of a 2-level full factorial experiment
design.
My question is: how i can do it with R, or best, what's the package who i
need to use for this purpose.
 


Thanks.

As I understand it, Yates' algorithm is just a faster (FFT-like) way to do
the normal hierarchical anova for a 2^n design, which aov() does via lm. In
my experience, these days aov is quite fast enough on a 2^n design for
feasible n (n <= 10, say).

On the other hand, Frank Yates wrote rather a lot, and this may not be what
you meant, in which case please ask again.
