DESCRIPTION

       RKWard is the a KDE-based GUI and IDE for the R scripting language for statistical
       computing.

       For more information, please refer to the RKWard website[1], and the documentation
       provided inside RKWard.

OPTIONS

       --evaluate Rcode
           The given R code is evaluated after RKWard has started, and after any specified
           workspace is loaded. Mostly useful for automated testing.

       --debug-level level
           Verbosity of debug output. 0-5, where 0 is no output, 5 is all output including
           function trace information. Default it 2.

       --debug-flags flags
           Allows to configure, which sections of code to debug. Flags are given as a binary
           number. Refer to the source files for documentation, as this really is an internal
           option.

       --debugger command [arguments [--]]
           Run RKWard through the specified debugger command. All arguments following this will
           be passed to the debugger command. To end debugger arguments (and add arguments to
           pass to RKWard), use "--".  NOTE: Only the frontend process will be debugged, using
           this option.

           Note that there are a number of pitfalls that may complicate setting up the debugger
           session as desired. Consider starting RKWard with option \-\-debug-lebel 3, which will
           print the effective command line used to start the frontend (but not all relevant
           environment variables). As one hint, you will generally need to pass a separator
           argument with the debugger arguments, e.g.  rkward --debugger gdb --args. Under
           Windows, the debugger command will not be connected to stdin. For interactive
           debugging, consider using a graphical debugger.

       --backend-debugger command
           Run the RKWard backend through the specified debugger command. To add command line
           options to the debugger command, enclose them in single quotes ('') together with the
           command.  NOTE: Debugger arguments will be split by spaces. If this is not
           appropriate, you will have to write your own wrapper script for invoking the debugger.
           Also, make sure to redirect all debugger output and/or input as appropriate. See the
           examples.

       --r-executable command
           In the case of several R installations, specify the installation to use, e.g.
           /usr/bin/R. Note that the rkward R library must have been installed to this
           installation of R, or startup will fail.

       --reuse
           If an instance of RKWard is already running, bring that to the front, and open
           files_to_open. Note that all other command line options will be ignored in case an
           instance is reused.

       files_to_open
           You can specify any number of file names or urls for RKWard to open. Usually this will
           be either workspace files, workplace files, R script files, or rkward://-urls (e.g.
           for starting with a plugin dialog). Specifying more than one workspace file will lead
           to the workspaces being merge together, and is not recommended.

EXAMPLES

           # Run the rkward backend through valgrind
           rkward --backend-debugger 'valgrind --log-file=valgrind.log'.
           # Debug the frontend through gdb
           rkward --debugger 'gdb --args'
