PostScript Graphics
Description
postscript starts the graphics device driver for producing
PostScript graphics.
The auxiliary function ps.options can be used to set and view
(if called without arguments)
default values for the arguments to postscript.
Usage
postscript(file = "Rplots.ps", ...)
ps.options(..., reset = FALSE, override.check = FALSE)
.PostScript.Options
Arguments
file |
a character string giving the name of the file to print to. |
... |
further options for |
paper |
the size of paper in the printer. The choices are
|
horizontal |
the orientation of the printed image, a logical. Defaults to true, that is landscape orientation. |
width, height |
the width and height of the graphics region in inches. The default is to use the entire page less a 0.25 inch border. |
family |
the font family to be used.
This must be one of |
pointsize |
the default point size to be used. |
bg |
the default background color to be used. |
fg |
the default foreground color to be used. |
onefile |
logical: if true (the default) allow multiple figures
in one file. If false, assume only one figure and give EPSF header
and no |
pagecentre |
logical: should the device region be centred on the page: defaults to true. |
print.it, append |
logical; are currently disregarded; just there for compatibility reasons. |
Details
postscript(..) opens the file file and the
PostScript commands needed to plot any graphics requested are
stored in that file.
This file can then be printed on a suitable device to obtain hard copy.
The postscript produced by R is EPS (Encapsulated PostScript)
compatible, and can be included into other documents, e.g. into LaTeX, using
\epsfig{file=<filename>}. For use in this way you will proabbly
want to set horizontal=FALSE, onefile=FALSE, paper="special".

check.options which is called from both
ps.options and postscript.
Examples
## Not run:
# open the file "foo.ps" for graphics output
postscript("foo.ps")
## End(Not run)
## Not run: dev.off() # turn off the postscript device
all(unlist(ps.options()) == unlist(.PostScript.Options))
ps.options(bg = "pink")
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:
str(ps.options(width=0:12, onefile=1, bg=pi, override.check = c(F,T,F)))
