統計数理研究所の中野先生の御世話でRに関する講演会が下記の要領(一部変更の可能性あり)で開かれることになりました。特に二日目は RjpWiki でもおなじみの顔ぶれがほとんどの、実質的な R ユーザー会になりますので、御参加のほどよろしくおねがいします。参加は自由でもちろん無料です。

以下中野先生からのメイルを転載:

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
communications.

 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.
