[R] RES: PostScript File Dimensions

[Rodrigo Aluizio]

Thanks David, you are absolutely right, the solution was more simple than I
was wondering, sorry for the mistake.
I always read the help files and search the older topic of the list before
posting, but this time I wasn't able found out a solution for such a simple
thing. I got very closer to your suggestion with other tries I've not
included in my first mail. But I got an error saying "The image is to large"
and gave up. It was only a question of changing the width and height
values...

Once again thank you, I'll try harder a next time.

Rodrigo.

You may be new to R but that does not mean you should stay "new" to  
the help pages. It looks as though postscript() is ignoring your  
setEPS efforts,,, with perfectly legitimate reason since that is not a  
defined parameter for that function. It is a separate function. What  
happens when you use the height= and width= parameters that the  
postscript help page defines for you? That "worked" for me (on a Mac  
OS X 10.5.5/ R2.8.0-64bit GUI device). Or you could try executing  
setEPS before your postscript call.

Further questions, as is always the case with output sorts of  
questions, should include your systemInfo. This is an example in the  
help page with an added plot. to make the otherwise blank 4 x 3 eps  
file look more interesting:

 > postscript("cm_test.eps", width = 4.0, height = 3.0,
+            horizontal = FALSE, onefile = FALSE, paper = "special",
+            family = "ComputerModern", encoding = "TeXtext.enc")
 > plot(1:10,10:1)
 > dev.off()
