[R] Fwd: About classification methods.

[Jaeik Cho]

Yes, this point i can understand your suggestion and I should read "HOW TO ASK GOOD QUESTIONS".
I'm a just new mailing list, also a R user for researching on graduate school.

Any person can make mistake, also it can be effect to other people, however a good person is teaching good way.
Anyway, actually I couldn't understand why you telling me like this, but sorry for my English and stupid first mailing list user.

Sorry again.

ps. I don't know also why should I put your name on CC Bert, sorry.
Last of all, R is a kind of professional software. It means many of R user is high level educated person at least I think.
Also, so many foreigner using this software who is not good for English writing. Please little bit more understand foreign users.

Thanks.

There may be a language issue and without implying any moral issue, the provision of a worked example might be even more important here than it would be in a situation of a shared language.  You might also consult the "How to ask good questions" link which IIRC is at the bottom of that document.
