[R] lattice dotplot reorder contiguous levels

[Bert Gunter]

I don't entirely understand what you want as an alternative. What is
wrong with relation ="same", the default?

In any case, it sounds like you'll need to write your own panel
function. If you look at panel.dotplot(), you'll see it's fairly
straightforward, so modification should not be difficult.

BTW, thanks for the reproducible example. I wouldn't have bothered at
all without it, although maybe the result is the same so far as your
concerned.

Cheers,
Bert
