Hi. Have you looked at graphviz? I have previously used R to generate graphviz diagrams. I create a template graphviz diagram and then use R to parse this template, substitute appropriate values and then outputto a temporary file. I then use a system() call to run graphviz on thisoutputted intermediary file to generate a PDF which is then incorporated into a report using Sweave. There is an Rgraphviz package, but I simply used a system() call instead.
I use RODBC to extract data directly from my research databases. I've used it to generate pretty publication-quality graphs showing patient recruitment, drop-outs etc., with patient numbers updated every time it is run! Hope this helps, Best wishes, Mark 2009/5/29 George Chen <glc...@stanford.edu>: > Hi, > > I would like to represent the treatment course of a subject with an arrow > representing passage through time and various ticks, arrows, or bars > representing treatments done to the patient along the arrow.
