R help - Apr 2009 - Cross-platforms solution to export R graphs

Hello Rusers,

I have worked on a R Wiki page for solutions in exporting R graphs, 
especially, the often-asked questions:
- How can I export R graphs in vectorized format (EMF) for inclusion in 
  MS Word or OpenOffice outside of Windows?
- What is the best solution(s) for post-editing/annotating R graphs.

The page is at: 
http://wiki.r-project.org/rwiki/doku.php?id=tips:graphics-misc:export.

I would be happy to receive your comments and suggestions to improve 
this document.
All the best,

PhG

Thank you Philippe. 
That is very helpful.

Well, if you insist ...

The PDF import plugin in OpenOffice is still beta, and some report deem
it difficult to install correctly an/or flaky.  Having checked that both
MSWord (>=2000) and OpenOffice (>=2.4) import and display correctly (i.
e. vectorially, including fonts) EPS files, I switched to this format,
most notably for use with the marvellous Max Kuhn's odfWeave package,
which is a *must* for us working in state/administrative/corporate salt
mines, where \LaTeX is deemed obscene and plain \TeX causes seizures ...
The point is that this format doesn't need any intermediary step, thus
allowing for automatisation. Be aware, however, that the embedded EPS
images are not editable in-place by OpenOffice nor, as far as I know, by
MS Word. But my point was to *avoid* post-production as much as humanly
possible (I tend to be inhumanly lazy...).

There is playwith, and latticist, which seem cross-platform (binaries
available for both Mac&Win). rattle uses latticist.
Rcmdr can be used for saving graphs.
JavaGD (used in JGR) saves PDF and EPS plots, but I was not very happy
with the quality of the graphics saved.

The article suggests to use Inksacpe for PDF -> SVG conversion.
I've recently experimented this, but it seems that the graph loses
quality in the way. The resulting SVG seems pixelised and doesn't look
very well when zoomed. I searched within Inkscape, but found no
relevant options (only the resolution for export).
Would there be options to look out for in Inkscape (such as antialias,
or else)?

Yes, right.

It is just a GUI on top of the described R functions.

Yes, I should try.

LaTeX is my personal tool of choice and the vector format I use most often
is  http://sourceforge.net/projects/pgf/ PGF  (Portable Graphics Format),
implemented via a LaTeX package written by Till Tantu. There exists a very
nice converter called  http://sourceforge.net/projects/eps2pgf/ eps2pgf 
which is written in java and does an excellent job of translating R eps
output. The primary advantage of PGF is that figure text gets typeset by the
LaTeX engine instead of by R which unifies font choices and gives the final
document a very consistent, professional look. LaTeX commands, such as
mathematical typesetting, can also be embedded in the figure.

Along with a friend of mine, I have been working on a R package that extends
Sweave to include pgf graphics output. Currently 
http://www.rforge.net/pgfSweave pgfSweave  uses eps2pgf to perform the
conversions but a native R graphics device is planned to help speed up the
process. The package is currently very much a beta and has been developed
and tested on Mac OS X and runs quite well. Limited testing has been
conducted on Linux and Windows and we have produced documents on those
systems. Heavy development is expected to take place this summer.

PGF is a human-readable format and can be be easily annotated by adding
additional commands to the resulting file. However, editing the original
content is possible but difficult due to the lack of structure in the
eps2pgf output. The LaTeX environment can even be switched from pgfpicture
to tikzpicture which allows the use of TiKZ- a high level graphics language
built on top of PGF. TiKZ/PGF is easy to learn and the manual is one of the
best pieces of software documentation I have seen. 

Since I came across PGF a couple of years ago, Adobe Illustrator has
languished unused on my hard drive except for the occasional application of
Live Trace. An excellent showcase of PGF/TiKZ examples along with additional
tools is hosted at  http://www.texample.net Texample .

The end result of the PGF/TiKZ build process is a PDF which makes it very
portable.

All the best!
