R help - Apr 2009 - How to know what device I am using

Some years ago I wrote a plotting routine that was run
on both Linux & Windows computers.

There were some differences in the way the plot looked
from the windows device and the X11 device.

To ensure consistency I used
getOption("device"))
and made some changes to the plotting if the windows device was being used.

Using this routine again, years later, I now notice that
getOption("device") returns a function listing, but no longer a string
with the name of the device.

What is the best way to query which device is the default?

See

 	?dev.cur
and

 	?options

 	esp. the para on 'device' under 'Options set in package
grDevices'
