[R] Friedman test for replicated blocked data

You'll find something about this topic in:
 
Myles Hollander & Douglas A. Wolfe (1999), _Nonparametric
statistical methods_. 2nd edition, John Wiley & Sons. Chapter 7 

In Chapter 7.9 there is an extension to the balanced replicated
design. Notice also the comments 70 and 74 about the
motivation of the test and the approximation of the test
statistic and comment 77 for an extension to the general case
(unbalanced). 
They give further references for more details, too. 

Hope this will help you

Christoph
