[R-sig-ME] coding a certain model

[Lin, Shin]

Hello:
 
Does anyone know how to code the following?
 
As on page 162 of Mixed Effects Models in S and S-Plus by Pinheiro and Bates with the same b_i** and PSI** but with W_i = 
 
1 1 0 0                         1
1 0 1 0    Kronecker product    1 
1 1 1 1                         1
                                1 
 
The difference is in the last row of the 3x4 matrix. 
 
Granted, it's a weird model, but this situation actually mimics a biological scenario.  I'm guessing that the solution, if there is one, would be in the manipulation of the groupedData object (Oats in this case).
 
Thanks.
