Dimensions of a List

Thanks a lot for your reply...Exactly...I need the same...But can I store these numbers and hence can access further? In other words how do I extract the numbers/dimensions from this class?

 Is this what you want?

 > l=list(list(c(1,2),c(4,5),c(6,7)),list(c(11,22,33),c(44,55,66)))
 > str(l)

 List of 2
  $ :List of 3
  ..$ : num [1:2] 1 2
  ..$ : num [1:2] 4 5
  ..$ : num [1:2] 6 7
  $ :List of 2
  ..$ : num [1:3] 11 22 33
  ..$ : num [1:3] 44 55 66
