[R] Lattice: merged strips?

[Mike Lawrence]

As I understand it, Duncan MacKay's solution involves simply pasting  
the factors together, as in:

|_AX_|_AY_|_BX_|_BY_|

Which isn't quite as aesthetically pleasing as what I I'm looking for:

|___A___|___B___|
|_X_|_Y_|_X_|_Y_|

Any further suggestions?
