Nor should you expect it to work. 'wireframe' is a lattice function.  
You should be looking at 'grid.layout' in grid and 'grid.arrange' in  
gridExtra.

Please read ?lattice which will explain the major differences between  
base and lattice graphics. Also locate the FAQ item regarding why  
lattice graphs do not appear (as they would not with that code.)
