[R] Extracting and using Lattice x or y axis

[Albart Coster]

Dear list,

I am using Lattice graphics together with Grid. In order to get
completely good results, I would like to copy the X and Y axes from the
Lattice graphic and draw these in another Grid Viewport. Is there a way
to achieve this? 

I would be gratefull for your help,
