J displays <1 2 and , <1 2 identically -- you can't tell from the display that
the first is a scalar and the second is a one-element list. The utility bi
below boxes the items of non-scalars but displays scalars the way J does.
Experiment with this utility. Try bi i. 3 2 4 and bi <1 2 and
bi
I think the issue is due to the following difference.
$ < 2 4 $ i.8
$ }. 2; < 2 4 $ i.8

Hey Pascal,
You may be looking for symmetry where there is none. The following shows these
monadic verbs are acting as the dictionary suggests.

2 2 4

2 0 0 0
0 0 0 0
0 1 2 3
4 5 6 7
>@}. 2; < 2 4 $ i.8 NB. }. drops first item of argument, resulting
I am taking the shape after I have opened the item. I'd expect it (the
insides) to be the same whether I got the item from }. or {:

Not so strange. }. and {: are not equivalent, even on 2-element lists.

JHS has basic support for D3 (Data Driven Graphics) built into the
framework. See www.d3js.org).
Currently only line and pie plots are supported. The D3 facilities are
powerful and easy to use once you have basic familiarity with
html5/javascript/jquery/d3. It will be easy to add additional plot

Just poking around randomly, it seems as though I get the mostly the same
answers with x: and 21312313123123123123123123123x in J6 32 and 64.
I'd assume there are tests that ensure identical results (?), and this applies
to all versions and all supported platforms.
