useR! 2008 is almost done already. The last session I attended was in the Audimax, the largest lecture room of the conference site.

useR! 2008 is almost done already. The last session I attended was in the Audimax, the largest lecture room of the conference site. Focus of the majority of the presentations was on teaching R and of motivating people to use it. However, the most interesting presentation was on R Analytic Flow, a rather simple application aimed at providing a hierarchical overview of your complex analyses.<br />
<span id="more-478"></span><br />
<a href="http://www.ef-prime.com/products/ranalyticflow_en/index.html">R Analytic Flow</a> has something very simple, but very interesting to offer for especially the more complex projects. Earlier, I wrote a project called MORET to organize your analysis, and R Analytic Flow has something similar to offer. Basically, R Analytic Flow offers a hierarchical view of your analysis. Each node of the hierarchical tree contains a basic function with corresponding parameters, which are executable directly. Also, future versions will allow for caching, so that the entire workspace is saved in the corresponding node. In that way, complex and time-consuming calculations do not need to be repeated. This is something I will surely try (see: <a href="http://www.ef-prime.com/products/ranalyticflow_en/index.html">http://www.ef-prime.com</a>) and will help me to keep the overview on complex projects. </p>
<p><img src="http://i0.wp.com/www.rensenieuwenhuis.nl/wp-content/uploads/2008/08/r-analytic-flow.jpg?resize=252%2C190" alt="" title="r-analytic-flow" class="alignnone size-full wp-image-477" data-recalc-dims="1" /></p>
<p>Perhaps, R Analytic Flow might even help people to start using R-Project, which was more explicitly the purpose of the other presentations. I&#8217;ve seen Nicholas Lewin-Koh presenting how he implemented to R-Project the analyses that are quite standard and often performed on his medical department. To give students a better feel for statistics, Adrian Bowman wrote simulation modules for often used distributions and analyses. Richard Pugh from <a href="http://www.mango-solutions.com/">Mango Solutions</a> gave a nice presentation on the experiences of his company with teaching R-Project to people. I totally agree with him that at first a firm basis should be created, before the more interesting capabilities should be taught. </p>

<i>&#8220;Excuse me, are you the author of Curving Normality? I am quite a regular reader of your blog.&#8221;</i></p>
<p>I can&#8217;t think of a nicer place than the useR! conference to find my single reader. Or, at least, one of the not-all-that-much readers. He appeared to be a sociologist, quite involved in the German &#8216;blogosphere&#8217;.<br />
<span id="more-438"></span><br />
We ended up having lunch, while discussing differences between the Dutch and German sociological community. Apparently, there are not that many differences. Both have had a debate between proponents of quantitative and qualitative methodologies, and in both countries the quantitative groups seem to have &#8216;won&#8217; the discussion, in the sense that quantitative methods are gaining in influence and relative number of users. </p>
<p>Interestingly, he was amazed by the openness of American professors such as Douglas Bates, whose session we had both attended. When I attended the ECPR conference in Rennes, France, I had a similar discussion with a German PHD-student. It seems that in Germany the distance between student and professor is indeed a lot larger than in other countries.</p>
<p>Well, B., should you read this: it was nice meeting you, and hopefully we run into each other a couple of times more during the conference.</p>

I'm writing this on my way to Dortmund, Germany, where I will attend the <a href="http://www.statistik.uni-dortmund.de/useR-2008/">useR! conference</a>. All sorts of <a href="www.r-project.org">R-Project</a> users and experts will gather to talk and think about developments regarding this open-source software for advanced statistical analysis. 

I look forward to the experience, and some sessions in particular.

Expect some serious live blogging to be going on on this site.]]></description>

I&#8217;m writing this on my way to Dortmund, Germany, where I will attend the <a href="http://www.statistik.uni-dortmund.de/useR-2008/">useR! conference</a>. All sorts of <a href="www.r-project.org">R-Project</a> users and experts will gather to talk and think about developments regarding this open-source software for advanced statistical analysis. </p>
<p>I look forward to the experience, and some sessions in particular. The tutorials by <a href"http://www.statistik.uni-dortmund.de/useR-2008//tutorials/bates.html">Douglas Bates</a> and <a href="http://www.statistik.uni-dortmund.de/useR-2008//tutorials/harrell.html">Frank E. Harrell Jr.</a> should be something that will give a lot of food for thought. I have prepared some problems regarding mixed models and migration, so I hope that these questions can be answered. </p>
<p>Also, I&#8217;m excited about presenting my <a href="www.rensenieuwenhuis.nl/r-project/read-isi">Read.isi package</a> to the people attending this conference. <span id="more-434"></span> Already, it has been a while since I developed it, but being able to present it was a nice impulse to finish and polish it so that it could be made publicly available. I hope to receive some constructive feedback and perhaps an idea or two to develop it even further.</p>
<p>The number of presentations during this conference is rather enormous! I expect to attend to more than 25 presentations in three days. Supposedly there will be WIFI connection at the conference location, so expect some serious live-blogging on this site. I will primarily focus on sessions applicable to social sciences, with a personal preference for mixed models, data visualization, and facilities for large-scale (survey) research.</p>
