For those whose environment is not accepting of LaTeX, this is a very workable alternative to Sweave and LaTeX. Setup is easy. The only problem is that the ODF file format does not make it easy to produce high quality graphics because it does not have full support for PDFs. Therefore, PNGs become the output of choice, and with those, the text-size has to be twiddled so as not to suffer from jaggies. (By plotting big type sizes on oversize canvases.)
There is some hope that ODF file format will play nicer with PDF in the future, so I make do for now.
