Hi Simon,
Thanks for the detailed answer. I had considered all those
possibilities, and was hoping that I had just missed something obvious.
I have been using S4 classes in my own packages for quite a while. But
here, I didn't see any need to create my own class. Now, I may make my
own,
Kevin,
welcome to the S4 world! ;) There is really no good solution since S4 only
works at all if you attach the package since it relies on replacing the base S3
generic with its own - so the question remains what are your options to do it.
The most obvious is to simply add Depends: Rgraphviz
