I'll try next time around. I use code more often than figures, so it skips my mind.</p>highlight 0.2-5 - Yihuiurn:md5:09128879d4604a59f5618448ef9ab5762010-12-07T17:23:37+01:00Yihui<p>Thanks for the great job, Romain.</p>
<p>Is there a way to center the figures without affecting the code (still align to the left)? This driver does not use the Verbatim environment, and I don't want to manually insert LaTeX code like begin{center} around my figures. There is no way in Sweave to specify the alignment of figures, AFAIK. Currently I have to sacrifice the highlighting feature when I want to produce plots in Sweave (i.e. use Sweave's default Verbatim environment).</p>What would impressionnists do with R ? - Romainurn:md5:663e09ba251c4f29509d6f8aaa50d1e62010-11-25T12:44:04+01:00Romain<p>Perhaps. Feel free to get started with RGimp or GimpR.</p>
<p>Maybe something that allows to run R scripts within gimp, the same way you can (I think) run python and perl scripts to massage an image. See the plugin example : <a href="http://www.gimp.org/docs/scheme_plugin/sample_plugin.html" title="http://www.gimp.org/docs/scheme_plugin/sample_plugin.html" rel="nofollow">http://www.gimp.org/docs/scheme_plu...</a></p>
<p>No reason we should not be able to plug in Rcpp/RInside into the mix</p>

The other part of me thinks that in general it would probably be easier just to create an interface to the GIMP. Either way, this is a neat trick.

<p>Although it's late, I thought I'd share the one-liner for downloading the source data:<br />

But, yes, it´s not working (the problem of the multi-arch...). Anyway, when it´s ready I will have fun with your code <img src="/themes/default/smilies/smile.png" alt=":)" class="smiley" /> .</p>

<p>Many thanks for your time and attention.</p>What would impressionnists do with R ? - Romainurn:md5:1d71912a54d9ca06e654438191aa35292010-11-14T20:52:09+01:00Romain<p>Ah. Maybe the binary on rforge was not prepared for multi-arch version of R.</p>
<p>Can you try to un-install "png" and then install it from CRAN.</p>
<pre>
install.packages( "png" )
</pre>
<p>Otherwise, please report this to Simon Urbanek, who is the maintainer of "png".</p>

Failed with error: ‘package 'png' is not installed for 'arch=x64'’</p>
<p>And I downloaded it from your page and installed as a zip file. Anyway, thanks for the lines.</p>What would impressionnists do with R ? - Romainurn:md5:a4173783ed38d7509464b1bc46c342f42010-11-14T20:23:51+01:00Romain<p>Hi,</p>
<p>What do you mean by "it does not work" ? I certainly have run this on R 2.12.0, albeit on OSX. What error do you get.</p>
<p>There was the omission of loading both the grid and png package before the rest of the code, maybe this is related to it :</p>
<pre>
require( grid )
require( png )
</pre>

<p>Could you comment a bit on as.raster.jobjRef…<br />
using as.raster(image), I can get the array of rgb strings, is there a way to get integers directly or to convert it to pixmap format…</p>
<p>My interest is mostly in grey images, 8 and 16 bits</p>

<p>Thanks for the nice comments. I indeed use beamer, and I uploaded the whole thing here: <a href="http://francoisromain.free.fr/misc/chicago/chicago.zip" title="http://francoisromain.free.fr/misc/chicago/chicago.zip" rel="nofollow">http://francoisromain.free.fr/misc/...</a></p>
<p>once unzipped, you should go to the 2010-10-chicago directory and run</p>

You presentations have a great visual appeal. I wonder if you use Beamer to make them. If you use beamer, can you please (if possible) share the source code? In case you don't, which software do you use?</p>
<p>Thanks a lot for the information.</p>
