Session Format

useR! 2006 has two kinds of user-contributed sessions

which have different aims and formats: the useR! kaleidoscope sessions will give a broad overview of various activities while the useR! focus sessions will provide a discussion and exhibition forum for ideas, software tools and applications focusing on certain topics of interest. Here, the users are actually brought together for demonstrations and discussions.

useR! Kaleidoscope Sessions

These are semi-plenary sessions with oral presentations of 15 minutes each. The aim is to give an overview of the many different applications and usages of the R system that should appeal to a broader audience.

Technical details: All lecture rooms are equipped with a laptop and an LCD projector. All presenters should send a PDF (preferred) or PPT file with their presentation slides to by 2006-06-08 (unless the presenters need their own laptop for software demonstrations).

useR! Focus Sessions

These sessions focus on topics of special interest and their goal is to provoke fruitful discussions in the respective user communities (e.g. Robust Statistics or Econometrics etc.). They consist of two stages: 1. spotlight presentations and 2. a big discussion and exhibition forum.

First, the spotlight presentations take place in a lecture room and should give a structured introduction (in a discussion free-context) to the discussion forum: each participant can briefly advertise his/her project (in 15 or 5 minute oral presentations, respectively).
Second, presenters and audience move to the assembly hall where each focus session has an exhibition stand. The participants can demonstrate their software, explain the conceptual and computational background of their applications and discuss future directions and projects which should help to set the course for R software projects in the respective communities.

Technical details: For the spotlights, all presenters should send a PDF (preferred) or PPT file with their presentation slides to by 2006-06-08 (unless the presenters need their own laptop for software demonstrations). The latter option is only available for the long 15 minute spotlights (the first four spotlights in each focus session), all short 5 minute spotlight presenters need to send in their slides in advance to minimize the time for switching between the talks.
For the discussion and exhibition forum, each presenter should bring along a poster describing their project and a laptop that can be used for further interactive demonstrations. The poster should not be wider than 111cm (43.7in) and higher than 166.5cm (65.6in). Posters must be fastened with sticky tape (no pins). A supply of tape will be available. One LCD projector per focus session is available. For the discussion and exhibition forum, there is no formal schedule. It is up to the participants to either start with an organized demonstration/discussion or directly start discussions in smaller groups. In any case, coffee, soft drinks and light snacks will be available to create a relaxed but stimulating environment.
