Gets the default device options as given by predefined devices options adjusted for the default arguments of the device function.
devOptions(type=NULL, custom=TRUE, special=TRUE, inherits=FALSE, drop=TRUE,
options=list(), ..., reset=FALSE)If drop=TRUE and a single device is queries, a named list is
returned, otherwise a matrix is returned.
If a requested device is not implemented/supported on the current system,
then "empty" results are returned.
If options were set, that is, if named options were specified via
..., then the list is returned invisibly, otherwise not.
A character string or a device function specifying
the device to be queried. May also be a vector, for querying
device options for multiple devices.
If TRUE, also the default settings specific to this
function is returned. For more details, see below.
A logical. For more details, see below.
If TRUE, the global option is used if the
type-specific is not set (or NULL).
If TRUE and only one device type is queried, then
a list is returned, otherwise a matrix.
Optional named list of settings.
Optional named arguments for setting new defaults. For more details, see below.
If TRUE, the device options are reset to R defaults.
When setting device options, the getOption("devOptions")[[type]]
option is modified. This means that for such options to be effective,
any device function needs to query also such options, which for instance
is done by devNew().
Also, for certain devices (eps, pdf, postscript, quartz, windows and x11), builtin R device options are set.

If argument special is TRUE, then the 'width' and 'height'
options are adjusted according to the rules explained for
argument 'paper' in pdf, postscript,
and xfig.
# Tabulate some of the default settings for known devices
print(devOptions()[,c("width", "height", "bg", "fg", "pointsize")])
