R.oo and S4?
Please what I already wrote in my previous message of this thread. Also, everything in R.oo is based on S3 and it uses standard R constructs and data types to achieve what it does. You can submit packages based on R.oo, and there are several such packages on CRAN, see 'Reverse dependencies' on http://cran.r-project.org/web/packages/R.oo/. Who told you it is not possible? /Henik

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?

S3 and S4 are part of the core of R so they would presumably be the most used. ?S4 is an extension to S3 but adds strong typing and a number of other features. ?R.oo and proto are packages on CRAN which give access to different models of object oriented programming than S3 and S4. R.oo uses a more conventional model of OO than S3 or S4 that is probably closer to what you are used to if you are coming form another language while proto uses the prototype model (or pure object model). proto tends to apply in user interface applications and there is some info on which other packages make use of proto on the proto home page at: http://r-proto.googlecode.com On Mon, Oct 26, 2009 at 2:47 PM, Peng Yu <pengyu.ut at gmail.com> wrote:
There are different way to make R classes. I know R.oo and S4. I'm wondering which one is the current popular one. Which one is current recommended when make new R packages? Thank you!
