Kip, I enjoyed this problem. I created the following script to randomly
generate lists and then create the stemplot. Save in a new jijx. Then run
it. Remove the NB. in the second line to see another example. Do the same
for the third line. Removing the NB. from the fourth line will generate new
data. Hopefully it won't fail. Id appreciate inprovements within simple J
from anyone.

In these days I guess you could call it a stem plot "app". In any case,
when you understand any steps you can remove ] from a given line and it
will no longer provide that result. Eventually, if you remove them all, you
can make a stem plot of two digit numbers. I would have able to develop this
and then use it in a high school Probability and Statistics class.

Subject: Re: [Jprogramming] Table Adverb
But not a random mess. We can observe
0 1 2 3 (+ %)/ 0 1 2 3
_ 2 2.5 3.33333
0 1 2 3 (+ %)"0/ 0 1 2 3 NB. notice the diagonal
_ 1 0.5 0.333333
_ 2 1.5 1.33333
_ 3 2.5 2.33333
_ 4 3.5 3.33333
0 1 2 3 (+ %)table 0 1 2 3
+---+----------------------+
|+ %|0 |

|0 | 1 2 3 _ 2 2.5 3.33333|

+---+----------------------+
The body above is (part of "expected" heading) , diagonal . Perhaps a new
table adverb could restore 1 2 3 to the heading and display _ 2 2.5 3.33333
as the diagonal of the body, with spaces elsewhere in the body.
Or perhaps not. I don't know whether the behavior of (+ %)/ above is
typical for rank infinity arguments to adverb / .
