I think the email thread got hijacked... but a follow up to the original
join question...
Roger pointed out that I wasn't being logical (i.e. appending rank 1 to
rank 2 doesn't make sense).
... and if I do this, I now get back what I expected to see.
(0 2$0), i.2 2
0 1
2 3
So... I borrowed the idea of q's "reshape" and implemented it in J as a
helper verb. So far, it seems to be doing the trick.
thanks for the comments and help.
