As with all things related to lisp, you'll find people that claim it to be the best, or the worst. It seems those who take the middle ground are rare ... at least we can avoid the arguments about all those parentheses, though :-) http://en.wikipedia.org/wiki/Common_Lisp_Object_System -- Steve Lianoglou Graduate Student: Computational Systems Biology | Memorial Sloan-Kettering Cancer Center | Weill Medical College of Cornell University Contact Info: http://cbio.mskcc.org/~lianos/contact __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] OOP module
Thank you! As an R newbie I sometimes find it confusing that in R everything can be done in at least four different ways. My question about S4/OOP was motivated by the fact that those two class systems have the same designer (Chambers). It is as if Chambers has designed an "S5" system that has less shortcomings than S4. For instance, I find it incredibly ugly that S4 methods can be defined independently of their class definitions. At first glance, OOP seems more intuitive. I have no knowledge of R.oo or proto.  Cheers!!
