Sorry, I make a mistake... I meant :
what the difference between

setClass("myClass",
   representation("fatherClass",x="numeric")
   ....

or

setClass("myClass",
   representation(x="numeric"),
   contains="fatherClass"
   ....



> setClass("myClass",
>    representation(x="numeric"),
>    contains="fartherClass")

> seems more logical to me in sense of syntax (pay attention to setClass
> instead of setMethod and contains instead of containt), but both work
> apparently.
