The example worked in the previous version, but David Meyer has rewritten the 
whole package using grid functions. Figures are much nicer now, but 
documentations is a bit on the sparse side. I don't have the docs at hand 
currently, but I believe you should looks at strucplot to set the layout there, 
or use grid directly.
