Creating the Grouping Attribute
I have a data like the below:
I need to create another attribute to this data, indicating the groups. i.e., the values in this attribute should be like,
i.e., the first X1, X2, X3 belong to group1, the second X1, X2 and X3 to group2 and so on for 'n' number of groups...
How do i do this? I am attempting this so that i can then use the "Example2AttributePivoting".
