Package Features

This page gives an overview over the features currently implemented in the OpenRepGrid R package. Note that the most accurate list of features in always found in the documentation of the R package itself. We try to keep this list up-to-date though.

As the package development is an ongoing process there might be forms of analysis that have not yet been implemented. If you miss any features please make a suggestion for a new features or for an enhancement or modification of an old features under the bullet point Suggestions / Issues in the navigation sidebar.
