N2 - R is a language and environment for statistical computing and graphics. It is available as free software and can easily be extended by user contributed packages. This paper introduces the R package DAKS (version 1.0-0) developed by the authors for the theory of knowledge spaces in psychometrics. Knowledge space theory provides a theoretical framework for the modeling, assessment, and training of knowledge. It utilizes the idea that some pieces of knowledge may imply others, and is based on order and set theory. The package DAKS contains general functions, for instance, for switching between different formulations in knowledge space theory, a simulation tool, a graph drawing device for Hasse diagrams, and several data analysis methods for detecting implications between test items.
