GitLab's issues for stixbox

Description

            PURPOSE
-------
Stixbox is a statistics toolbox which provides distribution functions, datasets,
statistical tests and plotting facilities. 


WARNING
-------
1) Stixbox for Scilab 6 is available only for Windows and Linux users.
Indeed, Stixbox depends on the distfun and the linalg modules, that are not yet
recompiled for Scilab 6 for MacOS.

2) The following functions have changed:
 * regres(y,X)  => regress(y,X)
 * regresprint(fullstats) => regressprint(fullstats)
 * qqnorm(x) => normplot(x)
 * rexpweib() is removed. Now the distfun module does the job.
   Please replace
    x = rexpweib(n, l, a)
   with :
    distfuna = (1/l)**(1/a);
    distfunb = a;
    x = distfun_wblrnd(distfuna, distfunb, n, 1);

 Please update your existing codes.

Comment from Samuel Gougeon

-- January 14, 2018, 02:58:05 AM

Hello,

This release for Scilab 6 can't be loaded properly, due to a missing Apifun dependency.
Apifun was declared as an explicit dependency up to the 2.4 version, but this is no longer
the case for this 2.6 version, and apparently nested dependencies are not (longer?) well
managed by the atoms installer. So, i get the following error while loading stixbox:

---------
Start Distfun

Start Helptbx
WARNING: Toolbox "apifun" is required and is not installed.

Start Specfun

Start Makematrix

atomsLoad: The file '\loader.sce' from (apifun - 0.4.2) does not exist or is not read
accessible.
atomsLoad: An error occurred while loading 'apifun-0.4.2':
	exec: Cannot open file \loader.sce.
at line   335 of function        atomsLoad (
C:\Logiciels\scilab\scilab-branch-6.0\modules\atoms\macros\atomsLoad.sci line 351 )
at line     1 of executed string 
--------
It may also be an issue due to the ORDER of declared dependencies. To be investigated.
For the time being, it would be safer to declare again Apifun as an explicit dependency.

Regards

I no longer get any error while loading Stixbox with Scilab 6.0.1 / win7

Comment from Nils Petersen -- April 16, 2018, 09:50:34 PM

Hello,
it is not possible to install stixbox on MacOS under scilab version 6.0.1.
Do you have a solution for solving this problem?

Comment from Samuel Gougeon

Hello Nils,
May you provide more information about the failure on MacOS, and how you proceeded?
Did you get any error message, etc?

Hello,

I have the same problem as Nils. 
Here is what the console gives :
--> atomsInstall("stixbox")
at line    62 of function atomsGetVersions ( /Applications/scilab-
6.0.1.app/Contents/MacOS/share/scilab/modules/atoms/macros/atoms_internals/atomsGetVersions.sci

at line   233 of function atomsInstall     ( /Applications/scilab-

atomsGetVersions: Wrong value for input argument #1: "distfun" must be an
available atoms package 
name.

I looked for the dependencies of stixbox and I think that the problem comes from the fact
that both 
Distfun and Linear Algebra are not available on version 6.0.1 under MacOS.

You are definitely right. 
I am adding a warning about this restriction in the Description's header of the module.
Thanks for your investigation and for having pointed out this issue.

Comment from Anton Gurkov -- October 16, 2018, 05:54:43 PM

I suggest updating names of the functions regres() and regresprint() to the current 
versions regress() and regressprint() in the description. Probably, it also would be great

to mention fact of this renaming somewhere on this page. For me it was quite tricky to 
figure out why my old code with this function doesn't work anymore :) Thanks!

Thanks Anton for having pointed out this missing information (buried in the changelog, 
only available after installation).
The changelog for the 2.5+2.6 releases is now published on this page near the related 
file, and as warning in the description.
Please note that qqnorm() has also been renamed, and rexpweib() has been removed (with a 
proper replacement).

Stixbox is claimed to be available for OSX, but the disfun atoms module, which is a
dependency, is not 
available for this platform :

This is already reported as comment hereabove:
http://atoms.scilab.org/toolboxes/stixbox/2.6/#comment2981

Stixbox description includes a warning about this point:
WARNING
-------
1) Stixbox for Scilab 6 is available only for Windows and Linux users.
Indeed, Stixbox depends on the distfun and the linalg modules, that are not yet
recompiled for Scilab 6 for MacOS.

Since the module is made only of macros, it is rather artificial to split its binaries 
into four identical copies just renamed and declared according to supported OS.
So, the error is rather on the ATOMS side,
* either to be able to declare OSes even when only macros are involved.
  AFAIR, this wish is already reported, for the TCL cases (as for the /serial/ module)
  that is not supported by MacOSX.
* or/and to able to take dependencies availabilities (maybe also reported.
  to be confirmed)

Stixbox 2.6 for macOS and Scilab 6
==================================
Stixbox does not install in Scilab 6 cause the developer of Distfun and Linalg does not
provide binaries for macOS and Scilab 6.

I compiled both toolboxes and want to share it with the Scilab community. You can download
it at:

   hani-ibrahim.de/public/scilab/

Install both toolboxes via -->

   atomsInstall("~/Downloads/xxx_6.0-bin.x86_64.darwin.zip")

Then you can install Stixbox 2.6 with Atom's GUI or commandline as usual.

Have fun
