[R] Building a package using classes

[Sébastien Durand]

Hello,

I am looking for an efficient and complete free tutorial to learn how to properly use, create and manage classes and their methods.

I have build few R packages in the past but I was not going very far in class definition and so forth. So I wish to drastically improve my coding skills in R...

Any quick comments.

Thanks a lot for your time and consideration.

Sébastien.
