    Hi,

    I have an excel sheet with 30 attributes(30 columns).I want to select 1st,3rd,7th and 15th columns and write it into another excel sheet.But I don't know how to select the above mentioned attributes only to write.

    Thanks

    With respect, you really do not need RM for this, so why bother ?

    Hi Maria,

    in RapidMiner 4.6, the operator AttributeFilter allows to filter attributes by name, by type, and by other conditions (see parameter filter condition). Depending on how you would like to filter, the option invert filter may need to be set.

    Best regards,
    Ralf

    Hi Ralf,

    Thanks for your valuable information.But using this operator I can select only one attribute at a time.Actually I want to select more than one attributes.

    Thanks
    Maria.

    Maria,

    Excellent display of manners. If you had been able to understand my answer you would not have needed to bother Ralf. 
    <operator name="Root" class="Process" expanded="yes">
        <operator name="ExampleSetGenerator" class="ExampleSetGenerator">
            <parameter key="target_function"	value="polynomial"/>
        </operator>
        <operator name="FeatureNameFilter" class="FeatureNameFilter">
            <parameter key="skip_features_with_name"	value="att1|att2|att3"/>
        </operator>
    </operator>

    Hi haddock,

    Thanks for the help  :)

    What i really mean is if we are having an option in RM, which  operator will be suited for the same instead of working directly in excel sheet. 

    Thanks,
    Maria
