I just found this software called Beaker today - it's essentially a way to mash together several different data analysis and presentation languages, allowing output from one to seamlessly become input for the next. To be fair, this isn't too difficult to do manually as long as the data sets are properly organized, but it's frequently a pain to convert something like R output to a presentable format without a few extra steps. Beaker appears to handle that. It'll even export to LaTeX as far as I can tell, so I can put off learning that for another year or so!

I haven't had a chance to try it out yet, but if Beaker is really as helpful as it seems then it could really save me some time. It would be nice to automatically export sets of R code and output to pretty HTML, at least.
