expandDataFrame

An object of class <code>data.frame</code> with the unique response patterns and the number of frequencies

tabdata

freqName

Expand a summary table of unique response patterns to a full sized
data-set.

The purpose of this package is to factor out logic and
        math common to Item Response Theory fitting, diagnostics, and
        analysis. It is envisioned as core support code suitable for
        more specialized IRT packages to build upon. A version 1.0 will
        offer optimized, low-level functions to map parameters to
        response probabilities for a wide variety of dichotomous and
        polytomous item models.
