S4 slot of type connection [Sec=Unclassified]
I am having trouble declaring a slot of type "connection" or "file" in which to store a file connection.
I get a warning message when class definition is loaded:
In .completeClassSlots(ClassDef, where) :
undefined slot classes in definition of "Element": datafileConn(class "file")
Can anyone suggest what type I should be using for the slot. Type "connection" produces similar warnings plus error messages.
