[R] R.oo and S4?

[Peng Yu]

I'm very familiar with C++. In this sense, it is easier for me to
learn R.oo according to your advice. On the other hand, S3 and S4 are
the most used. I'm wondering what would be the best choice for me. Do
you have any recommendation considering the pros and cons of both
ways?

Is it true that packages based on R.oo can not be deposited to CRAN?
