Oops, the second class should have been A in the examples. Corrected
version:
setClass("B", representation=representation("A", extra="numeric))
setClass("B", representation=representation(extra="numeric"),
contains="A")
Are these the same? If not, how do they differ?
What about
setClass("B", representation=representation("A", extra="numeric"),
contains="A")
?
As far as I can tell, the Green Book doesn't talk about a contains
argument to setClass.
