Henry, Earlier I thought I couldn't use a function inside another function,
but it seems now that I can.
require '~addons/debug/dissect/dissect.ijs'
pas=: 13 :'(i.>:y)!y'
NB. BINOMIAL PROBABILITIES
bp=: 13 :' (pas x)*(y^ i.>:x)*(1-y)^ |. i.>:x'
ds 'pas 3'
ds '3(([: pas [) * (] ^ [: i. [: >: [)
Devon,
Load 'plot'
Move this line:
loopSurfacePlot (1 2 12);0 2p1 99
to the end after loopsurface is defined.

I just realized what I did. By mistake I wrote ds=: and realized it and
knew I had to restart jqt. When I did all was fine.
Sorry to bother you.

Are you sure? When I run
ds '2([: |: ([ = [: +/ [: |: #~ #: [: i. ^) #"1 [: |: #~ #: [: i. ^)4'
I get a valid display. There seems to be a weird () following the 2 in
your version.

Henry, After an upgrade a click on an array in a red box will appear in a
grid. Now hist 8 appears in the grid with a scroll bar. Impressive.

Thanks. I'm already finding ds useful. Linda

Here's something I gleaned from the J wiki - it's idiosyncratic code but it
works. Try

According to the 'Data' page, you supply the data as
x;y;z
where z is a table and x and y have the same shape as z. (x and y could
also be lists).

Hi Raul,
It looks to me as if the wiki version is providing an array of shape 100 100
and it is plotting the z values for each position (x,y) within the array. You
would just need to pick your parameter so that it corresponds to integer
positions that would map on to the array and then insert t

Here's a parametric plot (in this case, my x function is linear, so
all I'm doing is adjusting the x axis labels):

Here's a surface function plot (copied straight from the wiki):

I think this idea is implementable. I am spending all my free time on
dissect, or I would work on it now. The hard decisions are in the UI.

Thanks Linda,
I agree that a big part of understanding a boxed structure is the way you use
the tools that you have to deconstruct it. I think Henry touches on this as
well in his original post when he talks about the tools that might be available
to probe the noun. So it seems to be a combinat
Finding a square seems an old problem to me, search the archive for
substring(s).
After some time I even seemed to remember yesterday a (my?) solution, but since
I am in Italy with no J available, I'll check it when I'm home.
