A list within a list?

How are your lists being created?

You can add each list to a mega list in a for loop, or use lapply to run a function multiple times which outputs a list each time and these will automatically be put together into a mega list.

If these don't work for you then tell us more about how you are creating the inner lists (sample code helps).
