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 TRUE
, also the default settings specific to this
function is returned. For more details, see below.
A logical
. For more details, see below.
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.
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.
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
.
# NOT RUN {
# Tabulate some of the default settings for known devices
print(devOptions()[,c("width", "height", "bg", "fg", "pointsize")])
# }
