            Bug ID: 524931
           Summary: Setting the warning options fails.
    Classification: Applications
           Product: rkward
      Version First unspecified
       Reported In:
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: R Console
          Assignee: rkward-devel at kde.org
          Reporter: sebastian.weirich at iqb.hu-berlin.de
  Target Milestone: ---

Using the AppImage of RKWard Version 0.8.3 with R 4.6.1 in MX Linux 23.6, I've
encountered the following error:

STEPS TO REPRODUCE
> getOption(x="warn")
[1] 1              # I would have expeced zero here
> options(warn=0)
Fehler in options(warn = 1L, NULL) : ungültiges Argument
> getOption(x="warn")
[1] 1              # The warning option has not been changed. 


OBSERVED RESULT
getOption(x="warn") is 1

EXPECTED RESULT
getOption(x="warn") should be 0

SOFTWARE/OS VERSIONS
Operating System: MX Linux 23.6 Debian (I've also reproduced the error in
Windows 11 25H2)
KDE Plasma Version: 
KDE Frameworks Version: 6.25.0
Qt Version: 6.10.2

Falls Sie versuchen den Schritt oberhalb zu wiederholen, tritt dann das Problem
wieder auf (nein, manchmal, immer)?
The problem is reproducible after system restart. 

Falls zutreffend: Wenn Sie das Selbe in einer R-Sitzung außerhalb von RKWard
durchführen, treten dann die selben Probleme auf?
When I start R directly from terminal and enter the code shown above, the
problem does not occur. As expected, the following is displayed: 
> getOption(x=“warn”)
[1] 0 

RKWard ist in vielen verschiedenen Paketen erhältlich und manchmal sind
Probleme spezifisch für eine Art der Installation. Wie haben Sie RKWard
installiert (welche Datei(en) haben Sie heruntergeladen)?
I used the AppImage, but the problem was reproducible when I reinstalled RKWard
0.8.3 on Windows 11 as a test.
