Hi guys,

I still did not solve my problem properly! I have to compare the values of two lists of 250 numbers as a result of using the ?by function! 
List1 of 250
 $ 0   : num [1:28] 22 11 31...
 $ 1   : num [1:15] 12 14 9 ...
..
..
..
 - attr(*, "dim")= int 250
 - attr(*, "dimnames")=List of 1

List2 of 250
 $ 0   : num [1:24] 20 12 22...
 $ 1   : num [1:17] 11 12 19 ...
..
..
..
 - attr(*, "dim")= int 250
 - attr(*, "dimnames")=List of 1

So I want to compare each vector of 250 from list1 with all other 250 vectors in list2! Is this doable (list1$0 with list2$0, list2$1 ASO)?

Thank you in advance,
Christina
