Jay, R has Sweave, which IMHO, blows ODS out of the water. If you know
or are willing to learn LaTeX, you can combine R and LaTeX markup into a
single document, process it in R to generate the final TeX output and
the use latex/pdflatex to generate the final document, including
textual, tabular and graphic output. 

This approach is known as reproducible research and is my primary tool
for clinical trial reporting.

Frank Harrell has a page here:

  http://biostat.mc.vanderbilt.edu/twiki/bin/view/Main/StatReport

with some information and examples. The main Sweave page is here:

  http://www.statistik.lmu.de/~leisch/Sweave/

There is also a package called odfWeave, which enables Sweave style
functionality for OpenOffice documents in lieu of LaTeX. More
information here on CRAN:

HTH,
