R help - Nov 2008 - getting "small" graphs with Sweave using Rnews.sty

I'm sorry for having to post this, but I can't seem to find any 
solutions to this, which seems pretty simple, but then again...

I've started playing with the example r news project and wanted to start 
adding some graphs, but replacing:

\begin{figure}
\vspace*{.1in}
\framebox[\textwidth]{\hfill \raisebox{-.45in}{\rule{0in}{1in}}
                       A graph goes here \hfill}
\caption{\label{figure:onecolfig}
A normal figure only occupies one column.}
\end{figure}

yields a an empty box, which is good, with the following:

\begin{figure}
\vspace*{.1in}
<<fig=true,echo=false>>plot( rnorm( 100 ) )
@
\caption{A normal figure only occupies one column.}
\label{figure:onecolfig}
\end{figure}

which isn't good, or at least yields a "normal sized" graph that
starts
in the second column, when I run Sweave( "yourarticle.rnw" ) and the 
pdflatex wrapper

Is it possible, to get a "small" graphic this way, or should I write
out a temp graph as a pdf and include the graphic by constructing the
statement using Sweave?

Thanks for any advice,
Jeff.

Dear Jeff,

Have you tried to insert the graph at the indended position? That is
pasting

<<fig=true,echo=false>>plot( rnorm( 100 ) )
@

At the location of

A graph goes here

So the code would be

\begin{figure}
\vspace*{.1in}
\framebox[\textwidth]{\hfill \raisebox{-.45in}{\rule{0in}{1in}}
<<fig=true,echo=false>>plot( rnorm( 100 ) )
@
\hfill}
\caption{\label{figure:onecolfig}
A normal figure only occupies one column.}
\end{figure} 

HTH,

Thierry

It is difficult to understand what you mean because your example is not
complete. Trying to make a self-running example see below: could you
explain?

There are two ways to control the size of an Sweave graph:  by telling R 
the size you want, and by telling LaTeX how big to make it when you 
include it.

You tell R the size by using <<fig=true, width=w, height=h>>= (with
w
and h being numbers in units of inches).  You tell LaTeX
(assuming you're using the graphicx package) by using 
\setkeys{Gin}{width=w} (or maybe you'd want to set the height, but I 
usually just set the width and
let LaTeX scale the height accordingly).  The w here is a LaTeX measure 
such as \textwidth or 4in or whatever you like.

I find the font choices in R look a little bit too large if I tell R the 
actual size I want, so I generally use both: tell R I want the figure 
larger than I really want it, and then tell
LaTeX to shrink it to fit.
