ToInert and dismantle

Check out ?ToInert and ?dismantle. The former returns a result that is logically identical to what you want; it is just not presented visually as a tree. The latter displays the output in tree form, but includes details that you might find irrelevant. It would be relatively easy to convert the ToInert output to an explicitly presented tree by using the GraphTheory package and its DrawNetwork command.

Example:

ToInert(x+2*y*z^2);

Thank you for the reply

Thank you for the reply but I'm looking to take an expression in my procedure and output an informative representation of it as a graph, using the GraphTheory package.The trees were just examples on how the graph should look like.
I've read the documentation on both functions right now I'm trying to figure it out how to implement them in my procedure.

Oh

I didn't see your final answer....ok I will try that.

How to convert

JamesK — Tue, 12 Mar 2013 22:26:45 Z

I've looked in the Graph Theory package but I can't see any function that will help to convert the output of ToInert to a graph/tree and preserve the relationships between the operands in order to use the DrawNetwork command.I've tried again using 'op' on the output created by ToInert but that didn't work.Any suggestions?

I posted in the followup thread

@JamesK I just posted a module with the required functionality in your followup thread.
