[R] reading & understanding SVG?

[David Carlson]

I was able to grab the logos by bringing the .svg file into
Inkscape (open source .svg editor). The three logos are grouped
so you can select them and then paste them into another
document. Then you'll have to ungroup the three logos and select
each logo separately.

p.s.  I don't need to use R for this, though I'd prefer to stay
with 
something that's free, open-source software.  I tried GIMP, but
couldn't 
see how to access the layers.


Hi, Peter:

       Thanks.  I should have been more specific:  I'd like to
try to 
extract into 3 separate files the weapons of mass destruction
symbols 
from the "WMD_world_map.svg" image in the Wiikipedia article on
"Weapons 
of mass destruction" 
(https://upload.wikimedia.org/wikipedia/commons/1/1d/WMD_world_m
ap.svg).


       I've opened it in Emacs enough to see that it's a
structured text 
file consistent with what little I know about XML.  It looks to
me like 
a list, but without convenient names for the list components.


       Thanks again,
       Spencer


p.s.  I found the biohazard symbol by itself 
(https://upload.wikimedia.org/wikipedia/commons/c/c0/Biohazard_s
ymbol.svg), 
but I didn't find the radioactive and skull-and-crossbones
symbols in 
exactly that form.  (I didn't look seriously beyond Wikimedia
commons, 
because I'm making a video, and I want something I can release
under the
