One approach is using Sweave along with PSTricks, specifically the pst-tree package. More information and examples here: http://tug.org/PSTricks/main.cgi?file=pst-tree/pst-tree The Indian TUG also has a pretty decent tutorial series on using PSTricks here: http://sarovar.org/projects/pstricks/ with Chapter 11 focusing on creating trees: http://sarovar.org/frs/download.php/1188/chap11.pdf I use pst-tree (and pst-node) to create subject disposition flow charts and stratification trees for clinical studies. I create the framework for the TeX graphic and then use \Sexpr{}'s to fill in the counts, percentages, other annotation, etc. as required from the data.
