[R] Automatic code diagramming for R?

[Gabor Grothendieck]

findGlobals in the codetools package can find all the functions
that a function calls and you could construct a call graph
from that by combining that with RGraphviz in Bioconductor.

For example, the proto package can automatically create a graph
using RGraphviz showing the parent child relationship among the proto
objects in a program.  The graph at the top of the following page was generated
like that from the program that you can view by clicking on the image:
http://code.google.com/p/r-proto/wiki/Overview
Its mainly applicable if you use proto but does illustrate the use of
RGraphviz.
