Hi David - I believe there are a few output options for the DB query actor. Tokens emitted from it can be sent directly to the R actor or they can be transformed using some of the other utility actors included in Kepler. If you choose 'record' as the output type, I believe you will end up with a RecordToken (and then a data frame in R) If you choose 'array' as the output type, you should end up with a list of RecordTokens. If you first print your output to a Display actor, you will have a better idea of what kind of token manipulation you may need to perform in order to get exactly what you want. If you get a sample workflow put together, please send it our way for with specific questions. -ben
