R help - Jan 2007 - pretended size postscript and size of the graphic device window

Dear list members!

I've two questions concerning graphic export:

a) I want to export my graphics as PostScript files. in this way I use the
postscript() function. The tricky part is that they must have a pretended size
(7 x 7 cm) and an absoulte font size (10pt).
b) how can i (permanent) change the size of the graphic device window?

Best regards

If I understand you correctly, ?postscript contains all you need to
know, eg:

postscript(file="foo.eps", paper="special", onefile=FALSE, 
           width=7/2.54, height=7/2.54, pointsize=10, 
           horizontal=FALSE)
plot(rnorm(100), rnorm(100), main = "foo")
dev.off()

Is this what you wanted?

This may well depend on your OS (unstated). I was looking for this the
other day as the window is too big on my laptop - I didn't look to hard
though so it is no surprise that I did not find a solution.

See ?postscript and its arguments width, height, paper and pointsize.

For the postscript device, see ?ps.options.

Most of the graphics device functions take args to set their size.  You 
can create your own function and use it instead of the standard one, 
with different defaults:  e.g.

mywin <- function() windows(2,2)
options(device="mywin")


Now I'll get really tiny windows.  You can put these lines in your 
.Rprofile (see ?Startup) if you want them to happen in all sessions.
