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:
ftp://ftp.tex.ac.uk/tex-archive/info/epslatex.pdf
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:
