ps.options {grDevices} | R Documentation |
The auxiliary function ps.options
can be used to set or view
(if called without arguments) the default values for some of 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)
setEPS(...)
setPS(...)
... |
arguments |
reset |
logical: should the defaults be reset to their ‘factory-fresh’ values? |
override.check |
logical argument passed to
|
If both reset = TRUE
and ...
are supplied the defaults
are first reset to the ‘factory-fresh’ values and then the new
values are applied.
For backwards compatibility argument append
is accepted but
ignored with a warning.
setEPS
and setPS
are wrappers to set defaults
appropriate for figures for inclusion in documents (the default size
is 7 inches square unless width
or height
is supplied)
and for spooling to a PostScript printer respectively. For historical
reasons the latter is the ultimate default.
A named list of all the previous defaults. If ...
or
reset = TRUE
is supplied the result has the visibility flag
turned off.
