[kepler-users] Sequence to Record

[Chris.Peters at csiro.au]

Hi Ben,

Thanks for the suggestion. I have looked at this actor - and you need to pre-configure the input ports - which would mean that you knew the number of input arrays. In my case I don't know the number of input arrays - this is determined when the workflow runs.

cheers

Chris,
Have you tried using the Record Assembler actor to make a record from  
your various arrays?
That might be just the thing you need before hooking it up to an R  
actor.
