[SOLVED]Add a rank column

Hi all!

Just started with RapidMiner.
Got so far that I'm calculating what I want.
Ended up with this result:
38.898
42.052
43.455

Now, in the next step I only care about what place it is, so how do I add a column with 1, 2, 3?
It's not always three, it varies.

Kind regards
thomas

Hi,

Sort and Generate ID should do it.

Hi, yes it did.
But...

now I'm trying with Loop Values and Filter because I got data as:
1,23.256
1,35.655
2,56.899
2,57.122

Tried condition_class = attribute_value_filter but I get an error.
How should I set up the filter to process 1's and 2's (and 3's, 4's and ...) separate?

Ok, got it!

attribute=%{loop_value}

Now it's just a matter of merge, right?

Thanks!

propably,

maybe you need to know that append also appends collections.
