The posting guide says

 	Sometimes it helps to provide a small example that someone can
 	actually run.

which you did not do.

This makes it hard for us to pinpoint the error.

For me, this works

> mat <- diag(c("$\\sigma_1^2$","$\\sigma_2^2$"))
> xtable(mat)
% latex table generated in R 2.4.1 by xtable 1.4-2 package
% Mon Apr 16 12:27:54 2007
\begin{table}[ht]
\begin{center}
\begin{tabular}{rll}
   \hline
  & 1 & 2 \\
   \hline
1 & $\sigma_1^2$ & 0 \\
   2 & 0 & $\sigma_2^2$ \\
    \hline
\end{tabular}
\end{center}
\end{table}

and placing the text output in between

 	\documentclass{article}

 	\begin{document}

and

 	\end{document}

saving the file and running latex (or pdflatex) produces nicely set 
output with the Greek letter 'sigma' properly rendered.
