What is the best code available for simple general purpose
manipulation of tree (and/or directed graph) data structures in R?

Looking through CRAN, I see a bunch of packages for stastical
regression trees, but nothing that seems to provide an API for
manipulating tree data structures.  What I'm looking for is something
along the lines of an R version of the Tcllib ::struct::tree API
available for Tcl:

  http://wiki.tcl.tk/210
  http://tcllib.sourceforge.net/doc/struct_tree.html
  http://tcllib.sourceforge.net/doc/graph.html

Thanks!

Maybe the people working on graphical models have something you are 
looking for, see http://www.r-project.org/gR/.
Have you looked at the "dynamicGraph" package?

might also look at the graph packages (graph, RBGL, etc) in BioConductor.
