What is maplegend?

The legend engine mapsf spun out, now covering legend types the parent map package can draw.

maplegend draws the legends for base-R thematic maps, extracted from mapsf so both packages could evolve the legend vocabulary independently. It has been catching up to the map types it has to serve: 0.6.0 added choro_point, choro_line, and choro_symb for choropleth legends rendered on circles, lines, and symbols, following the histogram legend type in 0.4.0. Considerable effort has gone into behaving correctly when the plot aspect ratio is not 1, which required refactoring most of the package in 0.4.0 and still produced a proportional-symbol segment sizing fix in 0.6.3.

What is metatools?

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 legend engine mapsf spun out, now covering legend types the parent map package can draw.

◆ Current state

maplegend draws the legends for base-R thematic maps, extracted from mapsf so both packages could evolve the legend vocabulary independently. It has been catching up to the map types it has to serve: 0.6.0 added choro_point, choro_line, and choro_symb for choropleth legends rendered on circles, lines, and symbols, following the histogram legend type in 0.4.0. Considerable effort has gone into behaving correctly when the plot aspect ratio is not 1, which required refactoring most of the package in 0.4.0 and still produced a proportional-symbol segment sizing fix in 0.6.3.

◆ Where it's heading

This is a support library whose backlog is defined by its caller. Every legend type mapsf can produce needs a matching legend renderer, and the release notes are dominated by spacing, offset, and border details — box_cex for symbol spacing, NA box placement in horizontal choropleth legends, text overflow when no_data is set. The shared vocabulary with mapsf is being maintained deliberately, with val_rnd, val_big, and val_dec propagating through legend types release by release. Version numbering is not monotonic in this feed, with 0.4.0 published seconds after 0.5.0.

◆ Prediction

Expect the remaining combined map types to acquire matching legends and the val_* formatting arguments to reach the types that still lack them.

SDTM supplemental-qualifier merging got sturdier, then the package went quiet for two years.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.
