Dear R People: 

Could someone direct me to some documentation on the
difference between S3 and S4 classes, please?

For example, why would a person use one as opposed to another?
Maybe pros and cons of each?

Thanks in advance!

R Version 2.2.0 (I'm downloading the new one this afternoon!) Windows.

Happy New Year!
