octave-ll: Low-level Function Interfacing with Octave
In RcppOctave: Seamless Interface to Octave -- And Matlab

octave_start Initialize an Octave session.

octave_end clears and terminates the current Octave session.

octave_verbose toggles the verbosity of RcppOctave calls: messages tracks any function call, or conversion of objects between R and Octave (e.g. arguments and results).

octave_modules add the Octave modules that ship with RcppOctave to Octave loading path.

octave_start(verbose = FALSE, warnings = FALSE, force = FALSE)

octave_end(verbose = getOption("verbose"))

octave_verbose(value)

octave_modules(verbose = getOption("verbose"))

`verbose`	logical that toggle verbosity. In `octave_start`, it is the value used as the initial global verbosity state. If `TRUE` all calls and conversions between R and Octave produce diagnostic messages.
`warnings`	logical that indicates if Octave startup warnings
`force`	logical that indicates if Octave session should be reinitialised, even if one was previously started (not meant to be used by end-users). should be shown.
`value`	logical value to toggle verbosity
