facets_feature_coverage() summarizes how mfrmr maps
the main FACETS output-table, output-file, and graph-menu surface to package
functions. It is a surface-coverage guide, not a statement that estimands,
conditioning, extreme-score handling, degrees of freedom, or numerical
results are equivalent.
Use this helper before migration work when you need a public, user-facing answer to three questions:
which FACETS outputs have a close
mfrmrroute,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", "supported_with_caveat", "partial", "not_implemented",
"not_targeted")
)Value
A data.frame with columns:
FACETSAreaFACETSFeatureFACETSReferencemfrmrRouteStatusSurfaceCoverageStatisticalContractValidationEvidenceOperationalStatusCapabilityLimitationAlternative
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.
The current software reference target is FACETS 64-bit 4.5.1 (July 2026). Bibliographic references retain the title and edition of the consulted manual rather than silently relabelling a 4.5.0 manual as 4.5.1. External numerical agreement must be evaluated separately for a matched model and estimand.
Status meanings:
implemented: a package-native route covers the substantive output surface; this status alone does not claim an externally matched statistical contract.supported_with_caveat: a package-native route exists, but the output must be read with explicit identification, validation, or scope caveats.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 documented package scope.not_targeted: the feature is tied to FACETS UI, Web/Excel handoff, or another external program format and is outside the package scope.
The four contract axes are deliberately independent:
SurfaceCoveragerecords whether a corresponding package surface exists; familiar visual grammar belongs only to this axis.StatisticalContractrecords the package-native statistical scope and never implies a FACETS-matched estimand.ValidationEvidencerecords whether this table establishes matched external numerical evidence. It currently does not; that conclusion requires a separate comparison using a matched model and estimand.OperationalStatusrecords route availability. A package route being available does not makemfrmroperationally interchangeable with FACETS.

#> 24 No dedicated FACETS-style arbitrary X-Y plot wrapper.
