R help - Nov 2010 - Problems with points in plots when importing from pdf to an SVG editor

Dear R-users

When trying to import graphics from an pdf-file to a Vector graphics editor
(I use Inkscape, but i've confirmed the same problem on adobe products), all
points in the graphics turn out as "q"s.
This example displays the beaviour:

pdf(file="points are weird.pdf")
plot(1:5)
dev.off()

When importing the file to inkscape, I get five neatly arranged little
"q"s.
The obvious workaround would be to change the points into another plotting
character, but this isn't the first time i've encountered this
behaviour,
and it would be nice to solve it properly instead.
I realize this might not strictly be a question related to R, but if someone
who've encountered the problem has found a solution or workaround it would
be greatly appreciated.

Kind regards/
Rafael

Hi,

Try with RSvgDevice::devSVG()
I don't have any problems with either Inkscape or Illustrator (CS4)

HTH,
Ivan

Just read the help page :).
This is under "Note" in the ?pdf.


      On some systems the default plotting character ?pch = 1? is
      displayed in some PDF viewers incorrectly as a ?"q"? character.
      (These seem to be viewers based on the ?poppler? PDF rendering
      library). This may be due to incorrect or incomplete mapping of
      font names to those used by the system.  Adding the following
      lines to ?~/.fonts.conf? or ?/etc/fonts/local.conf? may circumvent
      this problem.



      <alias binding="same">
             <family>ZapfDingbats</family>
             <accept><family>Dingbats</family></accept>
      </alias>


I've found that in my case, this happens when viewing a PDF
with that plotting character under old versions of Evince, but
not newer.
