[Rd] Structure of the object: list() and attr()

[Gorjanc Gregor]

Hello!

I am writing code where I define objects with new class. When I started,
it was a simple data.frame with attributes, but it is getting more evolved
and I would like to hear any pros and cons to go for list structure,
where one "slot" would be a data.frame, while other "slots" would take over
role of attributes.

Lep pozdrav / With regards,
    Gregor Gorjanc
