Papers
Below is
a selection of papers by area, including pdf's of some
manuscripts. Please contact me for more reprints.
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.
Recent
publication on
both
published in WIREs in 2010
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':
- ``
Selection
Sequences
- Interactive Analysis of Massive Datasets"
M. Theus,
H. Hofmann, A.F.X. Wilhelm (1997)
in
Computer Science and Statistics, Proceedings of the 29th
Symposium on the Interface 1997.
- ``Selection
Sequences
in MANET"

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

Displays vs. Interactive Statistical Graphics",
M. Theus,
(1995)

Statistics, Vol. 10 Issue 2, pp. 113-127

Entry in
Update Volume of the Encyclopaedia of Statistical Science,
eds. S. Kotz & Johnson
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.
