I don't have a specific algorithm or approach in mind, just looking to portray text in an interesting fashion. The output I'm hoping for is something like the following called a "Phrase Network": > > http://manyeyes.alphaworks.ibm.com/manyeyes/page/Phrase_Net.html It looks like you need algorithms to position nodes in order to minimise edge lengths and overlap. A well known program which does that is graphviz. I am quite sure that no one has taken the effort to re-implement the algorithm in R, but there are many R packages that interact with graphviz. I would look for "graphviz" in www.rseek.org and procede from there. -- Johannes Hüsing There is something fascinating about science.
