----- Abstracts of Simon's talks  ------------------------------

 Abstract of talk 1:
  R is a very flexible and powerful software for statistical computing.
 It extensibility is leveraged by hundreds of packages offering a wide
 variety of tools in many areas in applied sciences. However, the is
 one aspect that covered only partially and that is graphics. R
 produces high-quality static graphics for publication purposes, but
 it lacks interactive graphics for explorative data analysis.
  iPlots attempt to remedy this shortcoming by providing platform-
 independent interactive graphics for R. The iPlots package offers a
 wide range of fully interactive graphics including scatterplots,
 histograms, barchars, mosaic plots, parallel coordinates plots and
 many others. Moreover iPlots are based on a very flexible and
 extensible engine for creation of arbitrary interactive graphics: iBase.
  In this talk we will demonstrate the use of iPlots as a tool for
 exploratory data analysis and discuss the basic concepts of iPlots.
 We will also provide insights into the iBase framework for creating
 new interactive graphics. All this will demonstrated on practical
 real-word examples.
 Abstract of talk 2:
  R can be made accessible to a broader range of users by using
 graphical user interface (GUI) to provide additional support for the
 user. JGR - Java GUI for R is a cross-platoform GUI for R. It
 flattens the learning curve, is valuable for teaching statistics, but
 also includes features that will be welcome even by power-users.
  In this talk we will demonstrate various features of JGR, such as the
 intelligent console, code editor, object browser, help system and
 package installer. In addition we will discuss integration of iPlots
 (interactive graphics for R) and iWidgets (custom user interface
 elements in R) in JGR.
  We will also look behind the scenes and consider several R/Java
 interfaces, their differences and applications. Furthermore we will
 show how to integrate own Java code into R and use R function from
 within Java.
 Abstract of talk 3:
  For historical reasons, R is a single-threaded application. Nevertheless,
 in this talk we will show how can R be successfully
 leveraged for parallel computing. Most common approaches involve
 running several R processes using various kinds of inter-process
  In this talk we will discuss several different methods of parallel
 computing in R. We will also show step by stop how parallel computing
 can be made easy using the snow package for R. In addition, we will
 present in detail a practical example of model space exploration of
 tree models that we performed using massive parallel computing.
