ADE 4

Ade 4 was written by some professors (Jean Thioulouse, Daniel Chessel, Sylvain Doledec and Jean-Michel Olivier) of the Univ.Lyon, France, and its development is supported by contracts with the French Ministère de l'Environnement and the French National Center for Scientific Research(CNRS).
Ade 4 is usually useful in the context of environmental data analysis, but it can be also used in other scientific disciplines.

In particular, in multivariate statistics, Ade 4 can perform the following analysis methods:
-correspondence analysis
-principal component analysis
-discriminant analysis
-canonical correspondence analysis
-many regression methods
It has great graphical display capabilities, you can build graphs easily from data matrix, and then you can change these visualizations in various ways.

Ade 4 is made of several stand-alone applications, called modules, each of them can perform a range of analysis, and a set of graphical applications that show various kinds of visualizations for each analysis. Each module has various options about the kind of analysis to perform and the data to enter. Then the outputs are visualized in a text file. All the modules are managed through an interface, by which you can also see the current work directory and access various data sets included in the Ade-Data database.
On the Ade 4 website, besides the various modules and the user interface, you can download as well all the documentation (in pdf format), which explain the different analysis methods. You can open this documentation by the user interface,too.
Ade 4 is available for Windows and Macintosh (but there isn't a Linux version), and it is downloadable freely here: you have to download all the modules (or only those you need) from the "SeparateModules..." folder, and the interface from the "MetaCard" folder.
Now Ade 4 is available, besides as a stand-alone software, also as a package for R.
