Hi,
Is there any way to access an element of a list without looping over the list nor using unlist? Just to avoid parsing a very long list.


For ex, how to find a vector of a length 2 in a list without using a loop?

l = list (c(1), c(2,3), c(1,2,3))
for (i in 1:length(l))
    if(length(l[[i]]==2){
        print (i)
        break
    }

Thanks

Carol
