Listing all different values for an attribute

alexman

Hi,

I would like to be able to list all the different values for an attribute. For example:

City L.A L.A L.A Boston Cleveland New York

Rapidminer GUI output would be in range column: L.A (3) Boston(1) Cleveland(1) New york(1)
to get the number of times that L.A appears I can use Statistics.Count but I need to have the city name values isolated (L.A, Boston Cleveland, and New York)
I need to do it with rapidminer API ... is there any function like .... List l = Attribute.getDifferentValues() ?

Thx a lot

Hi, there's a simple method for this:

Attribute at = null;
List<String> values = at.getMapping().getValues();

But keep in mind, that you will recieve every value known so far. It might be, that this value isn't contained in the actual data set you have. So some of the values might have count of 0.
