[R] problem clipping R postscript plots within latex

[Stephen Eglen]

hi,

I've noticed a small problem trying to include postscript plots
generated by R into a latex document.  Specifically, the latex package
graphicsx allow you to specify the bounding box of the postscript
file, so that you can just show _part_ of the postscript file if you
tell it to also clip the area outside of the bounding box.  I've
previously used this LaTeX feature without problems on postscript
files produced e.g. by gnuplot.  However, this doesn't work on R
files.  Here is a simple example:


% R --vanilla

R : Copyright 2000, The R Development Core Team
Version 1.1.0  (June 15, 2000)

> t <- runif(40);
> postscript(file="try.ps")
> plot(t)
> dev.off()
null device 
          1 

here is the sample latex file that should include try.ps and just show
the central part of that postscript file:

\documentclass[12pt]{article}

\usepackage{graphicx}

\begin{document}

\fbox{\includegraphics[bb=200 200 300 300,width=4cm,clip=true]{try.ps}}
\end{document}

However, when this is run through latex and dvips, the whole of try.ps,
rather than just a central region, is included in the output.

Has anyone else noticed this?  

Cheers, Stephen
