R help - Jan 2005 - Questions on Inserting R graphs in latex!

Hi,
I try to insert R graphs into a latex file and I am using a Texniccenter/MikTex
combination in my Windows XP. Here are the errors I got. Could someone give me
some clues?
 
In R, I did
> plot(sin(1:10), pch="+") 
> dev.print(device=postscript, "C:\\myFigure.eps",onefile=FALSE,
horizontal=FALSE, paper="special")
 
In latex, I did (myFigure.eps is in the same folder as my latex file)

\documentclass{slides} 
\usepackage{graphicx} 
\begin{document} 
It can be seen in Figure \ref{fig:myFigure}.
\begin{figure} 
        \begin{center} 
                \includegraphics[scale=0.9]{myFigure} 
        \end{center} 
  \caption{test statement} 
        \label{fig:myFigure} 
\end{figure} 
\end{document} 
 
I got th following errors while I used Ctrl+F7 to edit.
 
! LaTeX Error: Environment figure undefined.

This is not an R problem, but LaTeX.  

Seems like the `slides' document class you're using doesn't
recognize the
`figure' environment.  You should check that.

I seem to recall that you need to specify a driver option for graphicx, such
as `epsfig' for some such.  You should check the documentation for that
package.

An additional problem separate from it not recognizing the figure 
environment is that I guess you ran pdflatex (to get a .pdf file and not 
a .dvi) and this indeed accepts only files in the formats below.

Try:

pdf(file="c:/myfigure.pdf")
plot(sin(1:10), pch="+")
dev.off()
