The purpose of this package is to factor out logic and math common
to Item Factor Analysis fitting, diagnostics, and analysis. It is
envisioned as core support code suitable for more specialized IRT packages
to build upon. Complete access to optimized C functions are made available
with R_RegisterCCallable.

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.
