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().
This software is described in Pritikin & Falk (2020)
The idea behind RPF is modularity. Most item factor analysis software is not modular. Modularity facilitates more contributors and cross pollination between projects.
To get the current released version from CRAN:
There are a number of useful scripts in the
install -- Installs the package as quickly as possible. Skips
building the vignettes and documentation.
build -- Builds a source tarball
check -- Builds a source tarball and checks it
rox -- Re-generates the documentation.
test -- Runs the test suite using the uninstalled tests against the
autodep -- Recalculates the header file dependences
