LaTeX \varrho

Hi,

plot( <whatever> , xlab=expression(rho))

works fine and plots LaTeX's \rho. How can I plot \varrho ?

Don't think so.  What you get depends on the output device, but I think
you get PostScript's symbol font's rho.  (On my system, on both postscript
and x11 devices.)  That font does not have the equivalent of varrho
(although it does for varpsi).

The usual answer is to use pstricks with LaTeX to post-process the output.

Thanks to Prof. Ripley for the hint, maybe someone other is interested, so
I will shortly outline what "to use pstricks with LaTeX" means:

* get PSfrag	(e.g. www.dante.de)
* get graphics	(same url)
* create your ps-graphic in R and define "tags" e.g.
	
	postscript("myfile.ps")
	plot(..., xlab="rho", ylab="wrho")
	dev.off()
	system("ps2epsi myfile.ps")

* add 
	\usepackage{graphics}
	\usepackage{psfrag}

	to your LaTeX-File

* and now we reach the climax:

	\begin{figure}
	\begin{center}
	\psfrag{rho}{$\varrho$}		<-- this replaces rho with \varrho
	\psfrag{wrho}{$W(\varrho)$}	<-- this replaces wrho with W(\varrho)
	\includegraphics{myfile.epsi}
	\caption{wonderful R plotting \label{fig}}
	\end{center}
	\end{figure}

* run latex and dvips and enjoy :-)

Torsten
