            Bug ID: 427670
           Summary: Error at start and crash when conducting time series
           Product: rkward
           Version: unspecified
          Platform: Other
                OS: macOS
            Status: REPORTED
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: rkward-devel at kde.org
          Reporter: jake at weareunity.com
  Target Milestone: ---

SUMMARY


STEPS TO REPRODUCE
1. Open up and a fatal error pops up – The backend process failed to start with
exit code 6.
The R backend will be shut down immediately. This means, you can not use any
more functions that rely on it. I.e. you can do hardly anything at all, not
even save the workspace (but if you're lucky, R already did that). What you can
do, however, is save any open command-files, the output, or copy data out of
open data editors. Quit RKWard after that. Sorry!
2. Click analysis
3. Click time series and then box pierce

ADDITIONAL INFORMATION
---Problem description---
Please fill in the missing bits *in English*.

I encountered the error message quoted below. Additionally, I saw the following
symptoms:
The backend process failed to start with exit code 6.
The R backend will be shut down immediately. This means, you can not use any
more functions that rely on it. I.e. you can do hardly anything at all, not
even save the workspace (but if you're lucky, R already did that). What you can
do, however, is save any open command-files, the output, or copy data out of
open data editors. Quit RKWard after that. Sorry!

What - in detail - did you do directly before you encountered this problem?
Open the program

When you try to repeat the above, does the problem occur again (no, sometimes,
always)?
Yes every single time

If applicable: When doing the same thing in an R session outside of RKWard, do
you see the same problem?
No, I am not proficient in R. This is why I have downloaded Reward to try and
conduct statistics as I am very proficient in Stata

Do you have any further information that might help us to track this problem
down? In particular, if applicable, can you provide sample data and sample R
code to reproduce this problem?
I do not need any data 

RKWard is available in many different packagings, and sometimes problems are
specific to one method of installation. How did you install RKWard (which
file(s) did you download)?
The Mac version on your website
