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.
