grab par values without opening a graphics device

Question

Is it possible to grab the parameters from par without opening the graphics device? So for instance if I do:

opar <- par()[["mar"]]
opar

on my windows 7/linux mint 14/mac machines a graphics device is opened.

How can I grab the output without awakening the graphics device?

I am ignorant as to what that means. – Tyler Rinker Feb 25 '14 at 14:13 — Tyler Rinker, Feb 25 '14 at 14:13

No, because the parameters from par() are stored as a part of the graphics device.

Details

par() calls an internal c function (C_par()) that checks the current device using the c function GEcurrentDevice() which asks for the current device. If it cannot find a device, it starts one (source code). C_par() then adds the parameters to the device using the Query() function (source code).
