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 is 2.

       --debug-output where
           Where to send debug output. Default is to store it in a file in the temporary
           directory. Specifying "terminal" will write debug output to stderr, instead (useful
           for debugging startup problems). Note that debug output from the backend process is
           always stored in a file.

       --debug-flags flags
           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.

       --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.

       --nowarn-external
           Usually, when invoking RKWard plugins from the command line (i.e. when files_to_open
           contains urls of the form rkward://runplugin/...), RKWard will show a warning that
           such urls could be used to trigger malicious actions on your system. This warning
           applies specifically to links found on untrusted websites, or other untrusted external
           sources. If you want to script RKWard locally, you can avoid this warning by adding
           --nowarn-external to the command line.

       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 merged together, and is not recommended.

EXAMPLES

           # Start with the t-test dialog
           rkward --nowarn-external rkward://runplugin/rkward::t_test/
           # Open two script files in a running instance of RKWard (or in a fresh instance, if RKWard is not running)
           rkward --reuse file_a.R file_b.R

           # Run the rkward backend through valgrind
           rkward --backend-debugger 'valgrind --log-file=valgrind.log'
