0 margin for creating eps files

Hi!

You may try (from the R help):

dev.print(postscript, file = "some_name.eps", horizontal = FALSE, onefile 
= FALSE, paper = "special")

Dear all,

I am trying to create eps files of R plots (in Linux) so that I can import them into Word
(obviously in MS Windows). What I would like is for the files to be cropped so that there is no
margin around the actual plot, because I have no way of editing the files after they have been
created. I have tried using

par(mai=c(.75,.75,0,0))

in order to reduce the margin; it works fine when I create a plot on the screen, however when I
use

dev.copy2eps(file="FILENAME.eps")

to save to the eps file, the margin has returned. Could someone please tell what I am doing wrong,
should I be using different parameter to set the margins of the eps files.

Any help would be greatly appreciated.

Many Thanks

Rishabh

I think the easiest way to do this is to use Ghostview to "convert to
EPS", and have it recalculate the bounding box as it does so.  Since
it's working with a Postscript interpreter, it does the bounding box
calculation very accurately; playing around with margins is likely to
lead to inconsistencies depending on labels, etc.

I don't see any need for that in my examples: R did the calculation
right to the nearest bp (and that's the accuracy of bounding boxes).

I suspect you mean GSView (on Windows): ghostview (a Unix program) does 
not AFAIK have that option.

If you just want a tight bounding box, gs's bbox device will give it to 
you.  On Unix, 

gs -sDEVICE=bbox -dBATCH -dNOPAUSE -q file.eps

will do something like

%%BoundingBox: 0 0 278 283
%%HiResBoundingBox: 0.000000 0.000000 277.992018 282.023991

just copy the first one into the file.  That's how all the figures in my 
books are included, for example.

Hi,
 Thanks to everyone that replied. It seems that the solution was simpler than I thought. I was
using the wrong parameter. It should have been

	par( mar = c( .., .., .., ..) )

rather than

	par( mai = c( .., .., .., ..) )

After I changed that it works fine now.

Thanks
