In particular, if applicable, can you provide sample data and sample R code to reproduce this problem? ###Please fill in### 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)? ###Please fill in### ---Error Message--- Message code: r_engine_has_died The backend process failed to start with exit code 1. 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! ---Session Info--- RKWard version: 0.7.0b KDE Frameworks version (runtime): 5.43.0 KDE Frameworks version (compile time): 5.43.0 Qt version (runtime): 5.9.4 Windows runtime version (refer to QSysInfo documentation to translate code into human readable form): 0xc0 Local config directory: C:/Users/ronny/AppData/Local RKWard storage directory: C:/Users/ronny/.rkward/ Backend version (as known to the frontend): Debug message file (this may contain relevant diagnostic output in case of trouble): C:/Users/ronny/AppData/Local/Temp/rkward.frontend - backend not available or rk.sessionInfo() canceled -
Thanks for reporting! I used to see this problem on Windows, myself, occasionally, but have not seen it in quite a while. I assume it to be fixed (by virtue of using a more recent version of Qt). Should you see it again, with RKWard 0.7.1 or later, please open a new ticket.
