R graphs in LaTeX documents?

[Sorry, I forgot the dev.copy2eps alternative and to make the answer
complete so this answer could be refered to when others ask the same
question again I also added the 'paper="special' argument (as dev.copy2eps
do)]

You have to save your plots/figures in EPS format. EPS is basically the
same as PS (postscript), but it is a one-page document with a
"BoundingBox". 

Example

In [R]: 

Alternative 1: Generate the plot *first* and then the eps file
  ...
  plot(sin(1:10), pch="+")
  dev.copy2eps("myFigure.eps")
  ...

Alternative 2: Generate the plot *first* and then the eps file
               (basically the same result as the above)
  ...
  plot(sin(1:10), pch="+")
  dev.print(device=postscript, "myFigure.eps", 
            onefile=FALSE, horizontal=FALSE, paper="special")
  ...

Alternative 3: Generate the eps file directly *without* opening
               a plotting window first.
  ...
  postscript(file="myFigure.eps",
             onefile=FALSE, horizontal=FALSE, paper="special")
  plot(sin(1:10), pch="+")
  dev.off()
  ...

Note that the arguments 'onefile=FALSE, horizontal=FALSE' (and
'paper="special"') are important!

In LaTeX: 

  ...
  Bla bla see Figure~\ref{figMyFigure}.

  \begin{figure}[hbtp]
    \begin{center}
      % Scale the figure to have the height 80mm keeping 
      % the width/height ratio.
      \resizebox{!}{80mm}{\includegraphics{myFigure.eps}}
    \end{center}
    \caption{The data used...}
    \label{figMyFigure} % <-- NOTE: After \caption!
  \end{figure}
  ... 

This requires that you use "\usepackage{graphics}" or
"\usepackage{graphicx}" at the top your LaTeX document.

[This answer is a correction of my own answer in the "Re: [R] Latex 
Question" thread from Dec 7, 2001:

  http://www.r-project.org/nocvs/mail/r-help/2001/6836.html

where I forgot the argument 'horizontal=FALSE'.]

Good luck!
