Subject: Use of contains in S4 classes
setClass("B", representation=representation("B", extra="numeric))
setClass("B", representation=representation(extra="numeric"),
contains="B")
Are these the same? If not, how do they differ?
What about
setClass("B", representation=representation("B", extra="numeric"),
contains="B")
?
As far as I can tell, the Green Book doesn't talk about a contains
argument to setClass.
