How to compare common variables of two files?

kimjkkimjk Member Posts: 19 Maven
in Help
I have two csv files, a and b.

These two csv have a common variable 'c', and the other variables have different types and numbers.

'After creating a new variable aa in file a, if the value of variable c in both files is the same, fill aa with 0, otherwise fill with 1'

Can we make a conditional statement like this?

Creating a new variable is not difficult, but creating a condition to compare the values of two files is difficult.

Any help please?

thank you

    Hi!

    Connecting two datasets based on a common attribute is called "Join". There is an operator for it in RapidMiner.

    Depending on the requirements, you would use inner join (keeps only matching rows from both tables), left join (keeps all rows from the left table and matching rows from the right table), right or full outer join (keeps all rows, joins the matching ones).
