RGL is a 3D real-time rendering device driver system for R.
Multiple devices are managed at a time, where one has the current focus
that receives instructions from the R command-line.
The device design is oriented towards the R device metaphor. If you send
scene management instructions, and there's no device open, it will be opened
automatically.
Opened devices automatically get the current device focus. The focus may be
changed by using rgl.set().
rgl.quit() shuts down the rgl subsystem and all open devices,
detaches the package including the shared library and additional system libraries.
If rgl.open() fails (e.g. because X windows is not running, or its
DISPLAY variable is not set properly), then you can retry the initialization
by calling rgl.init(). Do not do this when windows have
already been successfully opened: they will be orphaned, with no way to
remove them other than closing R. In fact, it's probably a good idea not to do this
at all: quitting R and restarting it is a better solution.
