A side-by-side editorial comparison of maplegend and markdown — release velocity, themes, recent moves, and the top alternatives to consider.
Shared themes:r-package
maplegend vs markdown: at a glance
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 markdown?
A package that finished, declared itself done, and handed its core function to a successor.
The R markdown package spent 2023 adding real capability — fenced code block attributes, HTML widget rendering, compatibility shims for rmarkdown's document functions. Then 1.13 declared the package feature-complete and maintenance-only, naming litedown as where development continues. Version 2.0 completes that handover: mark(), the package's core function, is now a thin wrapper around litedown::mark(), and users are told to call litedown directly.

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.
markdown
0.0ANALYTICS
A package that finished, declared itself done, and handed its core function to a successor.
◆ Current state
The R markdown package spent 2023 adding real capability — fenced code block attributes, HTML widget rendering, compatibility shims for rmarkdown's document functions. Then 1.13 declared the package feature-complete and maintenance-only, naming litedown as where development continues. Version 2.0 completes that handover: mark(), the package's core function, is now a thin wrapper around litedown::mark(), and users are told to call litedown directly.
◆ Where it's heading
This is a controlled retirement rather than abandonment. The maintainer closed out the outstanding feature work first, announced the succession explicitly, and only then reduced the package to a compatibility surface. What remains is a stable shim for the installed base while new work happens in a package with a different name and scope.
◆ Prediction
Expect only CRAN-driven fixes here from now on, with any genuinely new rendering capability appearing in litedown instead. The entries state this policy directly, so the main open question is how long the wrapper is kept before deprecation warnings appear.
