R-related
Software
Much of the software development of the last years war
R-related. There is the iPlots project
with Simon Urbanek
and the R frontend called JGR (Java Gui for
R). This is joint work with Simon and Markus Helbig.
Interactive
Data
Visualization
My latest
software
project in Interactive Data Visualization is the Mondrian software.
A paper
on
- ``Statistical
Data Exploration and Geographical Informaton Visualization''
is published
in Exploring
Geovisualization by Dykes, McEachren and Kraak.
Much of my work
in data visualization and intercative graphics was related to the MANET
software. MANET is developed at the
Department
of Computational Statistics and Data Analysis at the University of
Augsburg in Germany.

Two papers
deal
espacially with selections in huge, highdimensional datasets, using
'Selection
Sequences':

Interface
1997.

Some other
work
on data visualization deals with the comparision of Trellis Displays
and
interactive graphical methods.

Interfaces
and Design
of Statistical Software
These two
papers
deal with topics which are more related to computer science issues, but
are essentially important for everybody who develops statistical
software.
Analysis
of Categorical
Data
All these
papers
are based on visualization techniques using mosaic plots, and compare
to
different graphical and parametric analysis techniques.
