| Merges the two dataframes (dataframe1 and dataframe2), inserting the events of the second | |
| dataframe inside the cases of the first dataframe. | |
| This is done using a background knowledge provided in the case_relations dataframe, where the cases of the two dataframes | |
| are put in relations. | |
| E.g., if in dataframe1 and dataframe2 there are two case ID columns (case:concept:name), | |
| they are put in relations by case_relations having two columns case:concept:name_LEFT and case:concept:name_RIGHT | |
| Parameters | |
| ----------------- | |
| dataframe1 | |
| Reference dataframe (in which the events of the other dataframe are inserted) | |
| dataframe2 | |
| Second dataframe (to insert in the cases of the first) | |
