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.
Have your read the Posting Guide yet?
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.
The fact that people asking and answering questions are highly
educated is even more reason for including more background and asking
a detailed question. My point, which seems to have been misunderstood,
is that using a formal language such as R (or mathematics) is probably
a superior method of getting the real questions across the language
barrier. At the moment your questions seem too vague to allow a
specific answer.
Thanks.

That predictions.
At this point my suggestion is that your (re?)-read the Posting
Guide and determine whether you have adhered to the level of detail
and specificity that is implied to be desirable or optimal for
questions to r-help. 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.
(My apologies to Bert if this was a question that he really was
hoping to answer.)

Which package should I using, and can I compare each classifier
result by
predictions?
By prediction on the training data, emphastically no. By
prediction on
new data not used for training, yes.
