Both R and pandas allow the user to do a[a < 0] and a[a < 0] = 0. So what I'm wondering is why not extend xray's indexing to also work on arrays that are the same shape and have the same labels as the original array?

The problem is that a[a < 0] in NumPy flattens arrays with more than one dimension. We can't do this in xray without doing something like pointwise indexing to flatten out the labels, too.
