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.
