Yes indeed.
This thread started with Daniel Sabath being told by
various people that looping over observations was hardly
ever necessary.
As it turns out, his example is one in which looping
over observations is at the heart of _one_ solution.
Another limitation of -rowsort- is its restriction
to integers.
On the whole, I prefer to use -reshape- for this
kind of problem.
