What is malariasimulation?

An individual-based malaria model that grew a second parasite species, then froze itself for reproducibility.

malariasimulation is an individual-based transmission model whose 2.0 line added a full Plasmodium vivax implementation alongside the existing P. falciparum one, including hypnozoites, competing hazards, vivax-specific drug handling, an equilibrium solution and dedicated outputs. The most recent entry is not a code release at all but a coordinated malariaverse_01_2025 tag applied across the package suite, freezing every package at a matching version so existing analyses can be reproduced after the suite moves on. The record here is thin, two entries spanning sixteen months, so the visible cadence understates the work in the underlying repository.

What is vellumwidget?

vellumwidget is dissolving its own API: interaction now lives in the plot spec, not the widget call.

vellumwidget compiles a vellum scene or a vellumplot plot into a self-contained client-side htmlwidget with hover, select, brush, lasso, pan/zoom and export, and no server round-trip. The two-way Shiny story is complete: interactions surface as reactive inputs keyed by output id, and vellumwidget_proxy() drives an already-rendered widget from the server without re-rendering it. The last two releases are fidelity work rather than new surface, calibrating hit-testing from the rendered positions of marks and rendering the raster base image at 2x for HiDPI screens.

malariasimulation vs vellumwidget: editorial side-by-side

M0.0

An individual-based malaria model that grew a second parasite species, then froze itself for reproducibility.

◆ Current state

malariasimulation is an individual-based transmission model whose 2.0 line added a full Plasmodium vivax implementation alongside the existing P. falciparum one, including hypnozoites, competing hazards, vivax-specific drug handling, an equilibrium solution and dedicated outputs. The most recent entry is not a code release at all but a coordinated malariaverse_01_2025 tag applied across the package suite, freezing every package at a matching version so existing analyses can be reproduced after the suite moves on. The record here is thin, two entries spanning sixteen months, so the visible cadence understates the work in the underlying repository.

◆ Where it's heading

The direction visible in these entries is toward being a suite rather than a package. The snapshot tag is explicit that packages are installed together at one tag rather than mixed with main, which is the versioning discipline of a research platform whose users publish against specific model versions. On the modelling side, the vivax work was not a parameter addition but a distinct biology, with immunity structures removed rather than reused, indicating the model now carries two species with genuinely different natural histories.

◆ Prediction

The snapshot describes itself as freezing state immediately before an upcoming update, so the next visible release should be that update across the suite rather than any single package. Whether it extends the vivax model or the falciparum one is not indicated here.

6.3

vellumwidget is dissolving its own API: interaction now lives in the plot spec, not the widget call.

◆ Current state

vellumwidget compiles a vellum scene or a vellumplot plot into a self-contained client-side htmlwidget with hover, select, brush, lasso, pan/zoom and export, and no server round-trip. The two-way Shiny story is complete: interactions surface as reactive inputs keyed by output id, and vellumwidget_proxy() drives an already-rendered widget from the server without re-rendering it. The last two releases are fidelity work rather than new surface, calibrating hit-testing from the rendered positions of marks and rendering the raster base image at 2x for HiDPI screens.

◆ Where it's heading

The direction is declarative. 0.7.0 removed the interaction-intent arguments from as_widget() outright, dropping the signature from roughly 36 arguments to 24 and moving highlight, filter and cross-filter into vellumplot's spec via select_point(), condition() and filter_by(). Each release since has enacted more of that compiled spec on the frozen scene, from conditional encodings to single-view filters to cross-view cross-filtering, leaving the widget as an interpreter of the plot rather than a configuration surface of its own. The bug fixes track the same theme the engine's do: measured geometry and rendered geometry must not drift.

◆ Prediction

The notes name the remaining hold-outs explicitly, saying hover_mode, crosshair, legend_click, select_mode and the tooltip-appearance arguments remain only until their spec equivalents land, so the next releases most likely move those into vellumplot and shrink as_widget() further. The scale binds flagged as following the filter work are the other stated next step.
