change attributes order

Hi there 

 

I have a data set with patient_ID and some other attributes as specific diseases that each column includes 1/0

ID         Diabetes        Hypertension     Depression 

102            1                        0                       1

 

So how can I generate a new attribute that includes all current diseases for each  patient_ID  such as trhis:

ID         Disease   

102      Diabetes, Depression 

 

any thought?

Thanks,

Abbas

    I'd take a very similar approach to @Telcontar120 to do this. 

    Macros are variables that you can generate and use within a process in many different ways.  In this example it's to take the attribute name and use it to replace values in your dataset. 

     

    Here is an example you can put into your RapidMiner.

     

    <?xml version="1.0" encoding="UTF-8"?><process version="8.1.001">
      <context>
        <input/>
        <output/>

    If you use Loop Attributes, you should be able to replace the 0/1 value with the name of the attribute itself or blank using an IF expression and a macro for the attribute name inside Generate Attributes.

    Then you can concatenate using Generate Attributes again to put that all together into a single attribute.  There might be other more elegant ways as well, but this one should work.

    Thanks, Brian.

    I haven't used Loop, macro or others that you mentioned before.
    Could you plese explain more for me?

     

    Thanks in asdvance,

    Thank you so much!

    it is an amazing solotion.

     

    May I have your email address to send you a sample of data set and out put as it seems there is a problem because just consider one of my attributes?

     

    Thanks again,

    Abbas
