Hi, I'd like to create a S4 class contains only one type of data.
However, the number of slots varies.
For example, I want to create a class "a", each slots in "a" contains
numeric value only.
> setClass("a", contains = "numeric")
If I want to create an object "a" with only one slot containing c(3,4),
I will write
> new("a", c(3,4))
What if I want to create another object "a" with three slots with c(3,4)
in the 1st slot, c(1,2) in the second, and c(0, 5) in the third?
