As other answers pointed out in a more complicated way already, you did already create a list of lists! It's just the odd output of R that confuses (everybody?). Try this:

  ..$ : num 1
  ..$ : num 2
 $ :List of 2
  ..$ : chr "a"
  ..$ : chr "b"

And the most simple construction would be this:

> str(list(list(1, 2), list("a", "b")))
List of 2
 $ :List of 2
  ..$ : num 1
  ..$ : num 2
 $ :List of 2
  ..$ : chr "a"
  ..$ : chr "b"
