hi
I am calculating the division between the number of seconds of a call "duracion" into 60 to turn them in minutes as a generated field (duracion/60), "duracion" is a integer type, but I get this error
1 error(s):
Cannot create example set meta data: '/' must have arguments of type 'numerical'
Cannot create example set meta data: '/' must have arguments of type 'numerical'
I dont understand why
someone knows?
thanks

Hi @sebastian_gonza,
I am not able to reproduce this bug : Generate a new attribute from an attribute set as integer don't cause a problem here.
(however I raise this error if the attribute is set as nominal).
So could you share your process and your dataset(s) ?
Regards,
Lionel

Sure, in addition I have a problem with the pivot table but I guess it will be fixed once the problem with the calculation is ok.
0 -
Have you tried ......to execute your process ....... ?
There is nothing wrong in your process, it works perfectly (although, in deed, the first Generate Attributes operator is displaying an error) :

Yes, but the columns name should by the ranges that I created in "duracion_range" and the values I know is counting which is ok, but I want to add the duration in muntes which is calculated before but is not being processed in the workflow.

Do you want a final result like this :
if yes, remove the last Pivot operator
If I misunderstood, can you describe exactly what you want to obtain, by giving an example.

Lionel

Sometimes this happens with macros---you can always force RapidMiner to treat an attribute as numerical (as long as it is a number) by using the eval() function and the attribute name in the Generate Attributes expression editor.

something like this, each attribute of duration range as a column and the amount of call made by each id that are in that range
ID 8-0 min 1232424 12 1324850 3 23403412 1 0 -
