nanoparquet
nanoparquet is chasing byte-level agreement with the Java and Rust Parquet readers, not feature count.
A side-by-side editorial comparison of mapsf and metatools — release velocity, themes, recent moves, and the top alternatives to consider.
Thematic mapping in base R that finally got a theming system, then spent two years polishing legends.
mapsf produces thematic maps on R's base graphics device — choropleths, proportional symbols, typology maps, rasters, and their combinations, with legends, scale bars, north arrows, and insets as composable elements. Version 1.0.0 was the structural release, introducing a theming system that deprecated eight scattered styling arguments and adding mf_png() and mf_svg() export helpers plus alpha transparency across map types. The 1.1.x and 1.2.x line since then has been steady refinement: background and extent control on the drawing functions, decimal and thousands-separator control in legends, and label placement arguments.
SDTM supplemental-qualifier merging got sturdier, then the package went quiet for two years.
metatools provides the utilities that build and check SDTM and ADaM datasets against their metadata in the pharmaverse. The 0.1.6 release in July 2024 is the substantive one: combine_supp() learned to handle zero-row supplemental data, to refuse QNAM columns already present in the source, and to route multiple QNAM values to the same IDVAR, alongside enhanced controlled-terminology checks and record-uniqueness verification. Nothing has shipped since.

The package has been consolidating control into fewer, more consistent places. Legend handling moved out to the maplegend package in 0.8.0 and the per-element mf_legend_* functions were deprecated in favor of arguments on the map calls themselves; theming replaced ad-hoc style arguments in 1.0.0; and recent releases keep propagating the same argument vocabulary — bg, extent, leg_val_rnd, leg_val_dec, leg_val_big — across every function that should accept it. Determinism is a visible concern too, with 1.2.1 fixing a seed so mf_distr() point positions stop moving between runs.
The recent releases are almost entirely argument-parity work across existing functions, so expect that to continue until the vocabulary is uniform rather than any new map type appearing.

Nothing has shipped since.
The package's development has been concentrated on one function, combine_supp(), which is where the messy realities of supplemental qualifiers surface — whitespace in join keys, empty supp datasets, colliding names. 0.1.6 also drew three first-time contributors, which is the healthiest signal in the history, but no release has followed. Sibling packages have meanwhile been dropping metatools as a dependency.
Without a release in two years the package looks stable rather than active; the plausible trigger is a controlled-terminology or dplyr change that forces the checks to be updated.
