Mark, First, the CombinatoricaPlots package at my web site no longer completely works with the new Combinatorica package, as the internal format for representing directed graphs has changed. I have not yet had a chance to bring it up to date. However, the regular plotting in Combinatorica has been greatly improved so there is less a need for CombinatoricaPlots. You can always extract the branch list and the vertices as the first two parts of a graph. Therefore, in special cases, it should not be that difficult to draw graphs in exactly the form you want. Just draw the arrows or lines and vertices, perhaps using a Switch statement to pick out special cases for special formatting. I have one complaint about the Help for Combinatorica. It is just one long notebook and it is very difficult to find a coherent discussion of specific commands. Perhaps the subject is so large that one just has to buy the book, but in the meantime it would be useful if the Help was at least structured into groups of related commands.

I'm looking for a package that plots graphs with the following 'features': - The format of each graph node can specified - The format of the edge connecting particular nodes can be sepecified As far as I can tell the DiscreteMath`Combinatorica` package can't do this, and the very nice package << DiscreteMath`CombinatoricaPlots` from David Park also can't. Looking at the CombinatoricaPlots package I see it allows you to specify a label for each graph node, and I'd like to be able to set the the 'VertexDirectives', 'EdgeDirectives', etc of each node in the graph - actually I'm plotting a tree. Any suggestions apprciated TIA Mark mailto:mvdv at spamcop.net http://www.bigfoot.com/~mvdv
