Since Moose always exports inner() and 'use PDL' does as
well, you'll need to "fix" the problem somehow.
Since the inner() exported by 'use PDL' is also accessible as
a method call, you can 'use PDL::Lite' to avoid exporting any
functions from PDL and call everything as a method.
A hack-ish but simple fix is to use Sub::Delete to remove
the PDL inner routine from main: before use-ing Moose.
For example, this gives a warning:
use PDL;
use Moose;
But this does not:
BEGIN {
use PDL;
use Sub::Delete;
delete_sub 'inner';
}
use Moose;
where I used a BEGIN{} block to make the delete_sub call
take place *before* the loading of Moose.
Hope this helps,
Chris

Dear all,
Thank you very much for your quick replies!!
I've got pdl() part.
So in order to make inner() NOT collide, I need to unexport inner() either
from Moose or PDL, PDL::Graphics::PLplot.
So you are saying I need to look into those modules and unexport either of
them...right???
ugghhhh....*_*
Is there an easy way to do that??
or do I need to unexport PDL or PDL::Graphics::PLplot and change inner() to
PDL::inner() and so on....
I just tried a following and it did not work...:
use Moose;
no strict;
use PDL;
use aliased 'PDL::Graphics::PLplot';
use strict;
thank you.
Sincerely,
Tsuyoshi Okita

Hi Tsuyoshi:
I've never used PDL and PDL::Graphics::PLplot with Moose. PDL list
folks:
have any of you had this problem and overcome it?
As to item 2, I think code like this for $y:
my $y = pdl(0,1,2,104,4,5,24,7,8,99);
would make things work. Currently, your $y is a reference
to a perl list, not a pdl object.

Hello,
Thank you for providing us PDL::Graphics::PLplot.
I have a several questions I need to ask. I could not find any mailing
list for PDL::Graphics::PLplot.
I just started to using PDL::Graphics::PLplot. So my questions might
sound silly to you, but I hope you can bear with it.
1. I attached a simple perl code. This is what happends.
if I add use Moose; it gives a following message:
This is because Moose enables the strict pragma and PDL
exports the inner() routine which apparently collides with another
declaration/definition of inner().
"Prototype mismatch: sub main::inner: none vs (;@) at (eval 168) line
8."
2. I have been trying to plot a bundle of data.
my $x = sequence(10);
my $y = [0,1,2,104,4,5,24,7,8,99];
$pl->xyplot($x, $y,);
$pl->close;
this code gives me this error message:
"Can't call method "minmax" on unblessed reference at
/usr/local/lib/perl/5.14.2/PDL/Graphics/PLplot.pm line 1595."
As Doug points out, the problem is that PDL::Graphics::PLplot takes
PDL objects as input rather than perl list/list-refs. If you need to use
both the list ref and a PDL object you can use the pdl() constructor
to make a "piddle" and the ->unpdl method to regenerate an
equivalent set of list refs.
I understand this has to do with $y. It works if I add my $y =
sequence(10);.
I looked into PDL::Graphics::PLplot site and plplot documents, but
nothing
mention about sequence().
I am sure you are busy, but if you can help me out, I would be grateful.
I'm glad Doug was able to help you out. I recommend joining the perldl
mailing list which is where PDL is supported and is usually the best
way to get help.

Thank you.
