I'm a developer of data visualization methods, mainly in R, and an historian of data visualization. Here are some of my web sites:

• Main web site:datavis.ca Everything! Books, online papers, software, ...
• Milestones Project:datavis.ca/milestones The entire history of data visualization: timeline, images, references, ...
• Book web pages:
  • DDAR: Discrete Data Analysis with R
  • History of Data Visualization
  • IN PROGRESS:Visualizing Multivariate Data and Models in R

See:packages for some descriptions and links to documentation.

• Multivariate linear models:

  • Hyphothesis-Error plots:heplots;
  • Canonical discriminant analysis:candisc;
  • Multivariate influence:mvinfluence;
  • Visualizing collinearity diagnostics:VisCollin;
  • Generalized ridge trace plots for ridge regression:genridge;
  • Matrix linear algebra:matlib;
  • Generalized ellipsoids:gellipsoid
  • Two-way tables a la Tukey:twoway

• Categorical data analysis:

  • Extensions of thevcd package:vcdExtra.
  • See also my course:Psy6136: Categorical Data Analysis
  • Nested dichotomies logistic regression: ThenestedLogit package fits often simpler models for polytomous (multi-category) response date than multinomial models.

• Data:

  • Datasets in the history of statistics:HistData
  • Data from Andre-Michel Guerry,Moral Statistics of France:Guerry;
  • Word pools used in studies of learning and memory:WordPools
  • The Lahman Baseball Data archive:Lahman
  • Quotes on statistics:statquotes
