Hi, I'm new with this excellent program; I need help to perform the following task: I have two csv files two common columns (ID and emotion) I would like to create a task to compare these two files and get as a result two documents in which are shown in one all the ids with the same emotion and in another the ids with different emotions; for example id 001 file A felicity emotion, B emotion sadness file will be placed in the file with different emotions. Could you tell me step by step how should I do? Thank you
