Hello, netters!

I need some help typesetting partitioned matrices in latex.  Consider 
the following:

	$$ 
	R = 
	\left( 
	\begin{array}{c|c} 
	A & B \\ \hline C & D \\ 
	\end{array}  \right) $$

In the above A, B, C, D are the partitions of R.  The partitioning
is being shown by solid lines (\hline  and |).  My advisor wants them
to be real partitioning symbols, i.e., a thin, dashed line.

Have you used these?  If so, may be you can help me.  I didn't
find anything in LaTeX manual.  Browsing through TeXBook I haven't
found anything so far.  Help!!
