knitr

I recently became aware of the kintr package http://yihui.name/knitr/ which is much more capable and easier to use than Sweave when creating dynamic 'reproducible research' reports that interweave LaTeX and R.

I learned today about an amazing new program for searching the PubMed literature database plus full text documents - this is called 'Quertle'  http://www.quertle.info/ 

I tried it out and quickly found an important and relevant paper that we hadn't found in an earlier more extensive conventional literature search.
