Good one. When I saw this thread beginning to lengthen, I thought: "Ask an unanswerable question and you get philosophy." Jim

The OP should note that lists in general *do not have* columns. Data
frames (which are a special case of lists) do have columns.
Lists have "*entries*" or "components". It is important to get your
terminology right and to understand the concepts that you are dealing
with. Slap-dash hammer and hope is a recipe for disaster, especially
in R.
