Can someone recommend some paper that makes clear the relation and
distinctions between vector and raster graphics, but especially with
some practical examples in regard to what is the relation between
page (height and width) and dpi.
I'm not aware of a paper, but it's really not rocket
Everything works fine to place them in a pdf file , or eps file, but
when it comes to have a high quality of 300 dpi these graphs are not
good. For example I open the eps file with Adobe Illustrator (AI)
and it shows that it is a 72dpi graph.
This is simply not true: it's an eps and thus of

I have come around several times from R to A. Illustrator, or A.
photoshop, and between them with PowerPoint. It is possible that the
last one I reported was from PowerPoint.
So from your postings it was made clear that postscript plot from R
produces a vector graph.

It is possible to embed a raster image inside eps, but AFAIK R does not do
this. Other than that, your questions do not apply to eps. Rendering resolution
only comes into play when you put it into a raster software (like photoshop) or
print it.
Beyond that, we don't know what you are doing
Thank you Jeff for your advice,
Maybe it was better my email subject to had been high quality R graphs
for publication instead of 300 dpi and eps.
a. In my latest response I was asking for any published paper/book
(written by anybody in the R list) that describes how R handles vector
graphs
Hi Aldi,
Perhaps this will help slightly:
Dots per inch (DPI) or points (pixels) per inch (PPI) = number of
pixels/number of inches.
there are several ways of specifying the size of a graphic in R. You
use the width and height argument regardless, but you can set a
third argument the units
You seem to be stuck on pixels and so forth. This should not be your concern.
You should (as Joshua said) specify the aspect ratio by indicating the real
dimensions of your graphic in your call to postscript (), but that image won't
become pixels until later, and your publisher will be the one
Hi,
I have a run of 5 graphs that I want to place them under the same page.
