```BinLists[l, {{-Infinity, Infinity}},
{Range[0, Max[l[[All, 2]]] + 3, 2]}]

Hello All

I Would like to split this array: l={{1, 0}, {1, 1}, {1, 2}, {2,
3}, {2, 4}}, by the second element of each group, to group what are
between 0-2, 2-4,4-6 and so on (just the second element)
Using BinLists look like a good idea. I get my desirable result
with:
BinLists[{{1, 0}, {1, 1}, {1, 2}, {2, 3}, {2, 4}}, {0, 10, 10},
{0, 10, 2}]

But I would like to don't have to put any struction to the first
element (the "{0, 10, 10}" information)
How I can ignore it? I tried something like
BinLists[{{1, 0}, {1, 1}, {1, 2}, {2, 3}, {2, 4}},None, {0, 10,
2}]
BinLists[{{1, 0}, {1, 1}, {1, 2}, {2, 3}, {2, 4}},Automatic,
{0, 10, 2}]
BinLists[{{1, 0}, {1, 1}, {1, 2}, {2, 3}, {2, 4}},All, {0, 10,
2}]
But isn't the way.
