facets_feature_coverage: FACETS Feature Coverage Matrix

In mfrmr: Estimation and Diagnostics for Many-Facet Measurement Models

FACETS Feature Coverage Matrix

Description

facets_feature_coverage() summarizes how the current mfrmr release maps the main FACETS output-table, output-file, and graph-menu surface to package functions.

Use this helper before migration work when you need a public, user-facing answer to three questions:

• which FACETS outputs have a close mfrmr route,

• which outputs are only partially covered by structured R objects,

• which FACETS-specific outputs are not implemented or intentionally outside the current package scope.

Usage

facets_feature_coverage(
  status = c("all", "implemented", "partial", "not_implemented", "not_targeted")
)

Arguments

status

Which rows to return. "all" returns the full matrix. Other values filter by the Status column.

Details

The matrix is based on the FACETS 64-bit output index, which lists output Tables 1–14, DIF/bias plots, R/Web plots, output files, and graph-menu curves. mfrmr intentionally prioritizes structured R tables and reusable plot data over exact FACETS line-printer output.

Status meanings:

• implemented: a package-native route covers the substantive output.

• partial: the concept is covered, but not the full FACETS formatting, option surface, file type, or external integration.

• not_implemented: a FACETS feature has no direct package-native route in the current release.

• not_targeted: the feature is tied to FACETS UI, Web/Excel handoff, or another external program format and is not a release goal.

Value

A data.frame with columns:

• FACETSArea

• FACETSFeature

• FACETSReference

• mfrmrRoute

• Status

• Scope

• GapOrBoundary

• Priority
