R + LaTeX formula

Hi,

what is actually the best method to include R-plots into LaTeX
documents?
At the moment i use 

postscript("myplot.eps", width = 12.0, height = 9.0, horizontal =
FALSE, 
onefile = TRUE, paper = "special",encoding = "TeXtext.enc")
plot(foo,bar)
dev.off()  

But it is a bit unhandy to scale later and its difficult to get nice 
formula in the plots.

And how should i write formulas on the axis or at specific points? 
Has someone had some effort in exporting plots to pstricks or pictex?

kind regards and thank you for reading so far,

As per the Details section of ?postscript:

The postscript produced for a single R plot is EPS (Encapsulated
PostScript) compatible, and can be included into other documents, e.g.,
into LaTeX, using \includegraphics{<filename>}. For use in this way you
will probably want to set horizontal = FALSE, onefile = FALSE, paper =
"special". Note that the bounding box is for the device region: if you
find the white space around the plot region excessive, reduce the
margins of the figure region via par(mar=).


In your code above, change 'onefile = TRUE' to 'onefile = FALSE'.

For scaling you can use the LaTeX \includegraphics directive along with
several height and width arguments, such as:

  \includegraphics[width=4in]{myplot.eps}
  \includegraphics[height=4in]{myplot.eps}
  \includegraphics[scale=0.75]{myplot.eps}
  \includegraphics[width=0.4\textwidth]{myplot.eps}

You might want to review the following document:

For including formulae in R plots, see ?plotmath. You can run
example(plotmath) and there are many posts in the r-help archives on
this.

Beyond the above, you may want to look into using SWeave, whereby you
can create entire documents, with nicely formatted tables and plots
directly from R code. More information here:
