cIRT
A choice-based IRT model published once in 2019 and kept compiling ever since
A side-by-side editorial comparison of fmtr and hubAdmin — release velocity, themes, recent moves, and the top alternatives to consider.
Rebuilding SAS's formatting layer in R, one format specification at a time
fmtr applies formats to R data the way SAS applies them: named format catalogues, format lists, and an fapply() that maps a specification onto a vector. It is part of a family of packages that reconstruct SAS reporting idioms in R, and it shares infrastructure with them — labels.data.frame() was moved out to the common package, which fmtr now depends on. The recent releases have been closing specific gaps against SAS's own format vocabulary.
The config-authoring half of hubverse, pinned to whatever the schema is doing this quarter
hubAdmin builds and validates the JSON configuration that defines a hubverse forecast hub — rounds, model tasks, output types, target metadata. It is the administrator-facing member of the hubverse family, sitting alongside the packages that read and evaluate hub data. Its release cadence is set almost entirely by the hubverse schema, which it has now tracked from v4.0.0 through v6.0.0.

The direction is parity, pursued in small increments. Quarter format codes were added because base R has none; the SAS best. format was reimplemented, then hardened against the variations people actually write; statistical summary helpers like fmt_mean_sd() and fmt_mean_stderr() cover the cell contents clinical tables need. The structural work is largely behind it, including the breaking 2022 move that handed labelling to a sibling package, so what remains is vocabulary coverage.
The pattern of adding a SAS format, then a release to handle its variants, suggests the next releases continue filling in format codes and summary helpers rather than changing how formats are applied.

Every release here is legible as schema-following. New schema properties become new arguments, new schema constraints become new validate_config() checks, and the package version is essentially a marker for which schema generation it can author. The one thread that is genuinely its own is ergonomics: session-level options for schema version and branch, support for in-development schema branches, and a steadily stricter validator that now catches duplicate properties and mismatched target keys before a hub goes live.
With v6.0.0 support only partially landed, the next releases most likely finish the additional_metadata migration across the remaining create_* functions.
