I'm trying to do the following:
> setClass("MyNode", representation(parent = "MyNode"))
[1] "MyNode"
Warning message:
undefined slot classes in definition of "MyNode": parent(class "MyNode")
I scanned the docs, but found nothing. The representation function has no
problem, it's the setClass function which gives the warning.
What I'm trying to understand is why have the warning - it seems to work
just fine when I instantiate the class. Can we add an argument to the
setClass to suppress the warning?
This question was asked previously, but not answered in any satisfactory way:
