New !!! SOMbrero is now on CRAN: http://cran.r-project.org/web/packages/SOMbrero

You can visit its Web User Interface: http://shiny.nathalievilla.org/sombrero (SOMbrero WUI, v1.0 related to SOMbrero v1.0). The web user interface can also be used directly from the package with the function sombreroGUI().

SOMbrero is an R package dedicated to online (also called “on-line”) Self-Organizing Maps. The version 0.4-1 of the package can be used to train SOMs for numeric datasets, contingency tables (algorithm “KORRESP” which is illustrated on the “presidentielles 2002” dataset: see user-friendly documentation) or for dissimilarity data (relational SOM, illustrated on a graph from the novel Les Misérables). It contains many graphical functions for helping the user to interpret the results, as well as quality functions and super-clustering.

Maintainer: Nathalie Villa-Vialaneix (SAMM, Université Paris 1)

Authors: Laura Bendhaïba, Madalina Olteanu, Nathalie Villa-Vialaneix

The authors are grateful to Nicolas for his help with the implementation of the “korresp” algorithm, to Patrick for the original implementation of the “korresp” algorithm on SAS and to Marie for useful discussions.
