unpack.2tier

a list containing the design matrix, spec,
  param, mean, cov, scores, and data

A design matrix can be used to compress a bifactor or
two-tier model into primary factors and a partition of
items into specific factors. This function unpacks the
design matrix such that the specific factors are given
their own separate loading across all the items.

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.
