R is a free software and programming language for statistics. There exist thousands of packages extending R’s functionality.

Several of these packages some of which I am maintaining offer functionalities for knowledge space theory.

  • kst: Basic functionalities for KST (using set representations)
  • kstMatrix: Basic functionalities for KST (using more efficient matrix representations)
  • kstIO: Functions for loading/saving KST files.
  • CDSS: Course-Dependent Skill Structures

Further R packages for KST include DAKS and pks.

Recently, I have also written an overview on R packages for KST.
