[R] Standard method for S4 object

[Christophe Genolini]

Hi the list,

I am defining a new class MyClass. Shortly, I will submit a package with 
it. Before, I would like to know if there is a kind of "non official 
list" of what method a new S4 object have.
More precisely, personnaly, I use 'print', 'summary' and 'plot' a lot. 
So for my new class, I define these 3 methods. Is there some other 
method that a R user can raisonnably expect ? Some "minimum basic tools"...

Thanks

Christophe
