Subject: Re: [Jprogramming] minor note: csv data
That's pretty clever. I like using
(#~2|i.@#) ": (;:'a b c d'),]&.>p:p:p:i.4 4
│a │b │c │d │
│13 │19 │43 │71 │
│163 │193 │293 │359 │
│463 │619 │743 │971 │
│1091│1181│1423│1601│
although now that it's come up, I realize (_2{:\}: ": ...) is a little shorter.
Either way, it lets you dodge the problem with non-unique rows but at the cost
of quite a few characters. Thanks for this version though--I am sure I will end
up using it!
