Hi Vince --
Not a solution, but a little understanding and a workaround. With C1,
what happens is that the 'names' attribute of ll gets transfered to
the 'names' attribute of the S4 instance.
> setClass("C1", contains="list")
[1] "C1"
> setClass("C2", contains="C1")
[1] "C2"
> ll <- list(a=1, b=2
can list names attributes be preserved through S4
class containment? seems to be so but only if the containment
relationship is direct ... see below.
> setClass("c1", contains="list")
[1] "c1"
> l1 = list(a=1, b=2)
> o1 = new("c1", l1)
> names(o1) # pleasant surprise
[1] "a" "b"
> setClass("c
