    Hi Od,

    And welcome! Before you take another step start working through the examples provided. This forum, especially at the moment, is full of posts from people who think they can guess how Rapidminer works, wrongly. So save yourself time, and work through the samples!

    Sure,

    Open RM, press on "Repositories" tab, select a process, drag and drop in process tab. Also try the tutorial in the help section.

    I repeat my question.
    I have data which i want to insert in RM for feature selection.
    but how RM will recognize if insert in xls format with only name states Classes etc
    maybe RM will mix all the things :(

    If you have Rapidminer 5.00 installed then the repositories view is there, period.

    Thansk.
    One more question is.
    If i make an excel file and define class and attributes  then how would RM understand which is class and which is attribute?

    OK, now we are ready to go, almost... Before going through the examples, take three minutes to take in a video...

    For Monty Python fans the voice is a real treat It is about getting data.... Excel data included.

    Seek, and ye shall find!
