You can use the generate attributes operator for that.
Use a combination of concat, replace and position.

Hi there,

RapidMiner ExampleSets consist like most dataframes of primitives, not of complex data structures. As in most dataframes, you cannot store dictionaries in ExampleSets.

Can you maybe describe your problem a bit more? Usually you need to think more SQL-ish to attack the problem properly.

Best,

Martin
