[SOLVED] Create a new attribute
is it possible to create a new attribute based on attribute values of different example set lines?
Example: my example set has 1 attribute (att1), now I'd like to create a new attribute (att2) as follows:
att2(1) = att1(1) + att1(2)
att2(2) = att1(2) + att1(3)
att2(3) = att1(3) + att1(4)
The basic question is how to access and combine different values of the same attribute.
