When I tried to use the Lattice book, I found that I could not locate  
the code that produced the example I remembered (Figure  and could not  
initially findo Figures 13.8 and 13.9 (because they were in the color  
plates section in chapter 3) that appeared to be the result for the  
section to which I was referred from chapter 6.5.  So I would suggest  
going to the book's website:

http://lmdvr.r-forge.r-project.org/figures/figures.html

and looking at the code for 13.9 and 6.5, both of which use cloud but  
I think the parameter you want is aspect, which is also in the  
parameter list for wireframe. Further examination of the wireframe  
help page examples suggests that you have not yet looked at that  
resource, since the first one uses aspect to create a rectangular  
bounding box.
