Dear Thomas
thank you for asking about this.
The main information in a graphNEL is, of course, the vector of nodes
(character) and a list of edges. That information can for sure go into an
igraph.
Then there is the slot `renderInfo`, which afaIu is (or can be) used to control
how the graph should be rendered when plotted e.g. on a 2D screen with
Rgraphivz. The last big refactoring seems (according to svn blame) due to Seth
Falcon, Nishant Gopalakrishnan and Florian Hahne in 2010/11. (The package has
been worked on by a variety of of people over the years; e.g. my own
involvement dates back to two bursts in 2004 and 07).
It is hard to tell how much of the renderInfo functionality is used out there
in the wild, but the fact that its code hasn’t been touched for 5 years is
consistent with assuming that interest in it is limited (otherwise there tend
to be bug reports or requests for more functionality).
Kapser and Florian are probably lurking on this list and waiting to make
additional comments.
In summary: I think your proposal is great, and you should go ahead. I expect
the downsides, if any, to be miniscule.
Hope this helps
Wolfgang
