[Solved] Shift all examples in an attribute by one

qwertz

Dear all,

I'm looking for a way to create a copy of the attributes which is shifted by one example compared to the original.

Original:
att1 att2
10 50
20 100
30 150

Expexted result:
att1 att1_shifted att2 att2_shifted
10 20 50 100
20 30 100 150
30 150


I tried with the "loop" and "macro" operators but until now I found no solution for this.
I'm always struggiling with these two parameters  



Cheers

Ok, here is what I found out so far. Not quite yet what I was looking for but maybe this could be an inspiration for all the brains out there...

Best regards
