Software

I am current developer and maintainer of the following R packages

  • clustrd - Joint Dimension Reduction and Clustering in R
  • idm - Incremental Decomposition Methods in R (incremental versions of Principal Components Analysis and Multiple Correspondence Analysis)
  • caGUI - a Tcl/Tk GUI for the functions of the ca package.

and the following standalone software written looong ago in Matlab & Delphi:

  • CHIC Analysis - Correspondence & HIerachical Cluster Analysis
  • Procrustes - Generalized Procrustes Analysis (in Greek)
