# [Xy-pic] (no subject)

I recently started using xy-pic in my lecture notes, but I can't seem to figure out how to horizontally align entries in an xymatrix.  I thought that '**[r]' would align the entry 'right', while '**[l]' would align the entry 'left'.  However, this doesn't seem to be the case with the following code (where I would like the 'xymatrix' and the 'array' to essentially have the same horizontal column alignment) ...

\documentclass[english]{article}

\usepackage[all]{xy}

\begin{document}

$\xymatrix{ A \times B & **[l] C \\ **[r] D & E \times F }$

$\begin{array}{rl} A \times B & C \\ D & E \times F \end{array}$

\end{document}

Any guidance would be very much appreciated.
