[R] Greek symbols in xtable rows

[Andris Jankevics]

Thank You for answer. I Tried code that You provided in reply to my question 
on both PC's with Linux and Widows OS.

On linux box output is:

> xtable(diag(c("$\\sigma_1^2$","$\\sigma_2^2$")))
% latex table generated in R 2.4.0 by xtable 1.4-3 package
% Tue Apr 17 09:18:31 2007
\begin{table}[ht]
\begin{center}
\begin{tabular}{rll}
  \hline
 & 1 & 2 \\
  \hline
1 & \$$\backslash$sigma\_1\verb|^|2\$ & 0 \\
  2 & 0 & \$$\backslash$sigma\_2\verb|^|2\$ \\
   \hline
\end{tabular}
\end{center}
\end{table}

And there is an output form my windows PC:

> xtable (mat)
