| ps.options {grDevices} | R Documentation |
The auxiliary function ps.options can be used to set and view
(if called without arguments) default values for the arguments to
postscript.
ps.options needs to be called before calling postscript,
and the default values it sets can be overridden by supplying
arguments to postscript.
ps.options(..., reset = FALSE, override.check = FALSE)
... |
arguments paper, horizontal, width,
height, family, encoding, pointsize,
bg, fg, onefile (unused), print.it,
append (unused), pagecentre,
command and colormodel can be supplied. |
reset, override.check |
logical arguments passed to
check.options. See the Examples. |
Note that despite the name, these settings also provide the defaults
for some of the arguments for pdf and
xfig, although not in all cases even when they have
arguments of the same name.
Arguments onefile and append are accepted but are unused
in any of the graphics devices making use of this function.
For pdf, arguments family, encoding
pointsize, bg, fg and pagecentre are used.
For xfig, arguments paper, horizontal,
width, height, family, pointsize,
bg, fg and pagecentre are used.
A named list of default values for arguments.
ps.options(bg = "pink")
utils::str(ps.options(reset = TRUE))
### ---- error checking of arguments: ----
ps.options(width=0:12, onefile=0, bg=pi)
# override the check for 'onefile', but not the others:
utils::str(ps.options(width=0:12, onefile=1, bg=pi,
override.check = c(FALSE,TRUE,FALSE)))
