Lattice Wireframe Plot into LaTex

Dear R/LaTex user,

I'm simply trying to include a plot created with the Lattice wireframe
function into LaTex. I have no problems including other R plots into LaTex
by exporting as a Postcript and then including the graph in LaTex using

\begin{figure}
   % Requires \usepackage{graphicx}
   \includegraphics[width=]{mygraph.eps}\\
   \caption{}\label{}
\end{figure}
However, for some reason when I do this with a wireframe plot I can see the
plot area in LaTex but not the plot itself.

I've search for this exhaustively on the web but couldn't find an answer.

I'll appreciate your help.

Thanks,
Lars.
