Suppose I have a length M list of lists, each sub-list is of the same length (N).
How could I efficiently refactor these lists so that I now have N lists of length M?

It would be similar to if you made a matrix of the lists and sliced by a different dimension.

I.E.

original <- list(list(1:3, 4:6), list(2:4, 5:7))
> final
[[1]]
[[1]][[1]]
1, 2, 3
[[1]][[2]]
2, 3, 4

[[2]]
[[2]][[1]]
4, 5, 6
[[2]]
[[2]][[2]]
5, 6, 7

@MatthewLundberg, I'll happily delete if it is. I searched around a bit without success on finding the original post. Please point me in the right direction – jameselmore Jul 21 '16 at 19:35

@MatthewLundberg I think you are right. Dupe tagged it. – akrun Jul 21 '16 at 19:37

@lmo That one is even less clear as to the desired behavior, but I think you're right. – Matthew Lundberg Jul 21 '16 at 19:42
