[R] Dimensions of a List

2008-03-25 Thread Shubha Vishwanath Karanth 
Hi R,

 

I have a list,

 

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

 

 l

[[1]]

[[1]][[1]]

[1] 1 2

 

[[1]][[2]]

[1] 4 5

 

[[1]][[3]]

[1] 6 7

 

 

[[2]]

[[2]][[1]]

[1] 11 22 33

 

[[2]][[2]]

[1] 44 55 66

 

 

How do I know the dimensions of this list?... In other words, how many
sub-lists, sub-sub-lists etc...are there in l? How do I know this?

 

Thanks in advance

Shubha

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?

Maybe something like this:

lis - lapply(l, lapply, length)
names(lis) - lapply(l, length)
