anivis (development version)

plot() works on an aniframe with nothing to draw (#32) — one with no rows, or one whose positions are all NA. Both failed with arguments imply differing number of rows: 0, 2, preceded by a warning about the each argument, neither of which pointed at the frame. The second case is the likelier one: a keypoint the tracker never found has no start or end to mark.

trajectory_endpoints() returned NULL when no group had a valid point — do.call(rbind, list()) — and nrow(NULL) then reached rep(each = ), which used a NULL length and produced two rows against a column of none.

The minimum anicore is 0.8.0, which is the first version published under that name. The constraint read >= 0.6.0 — a version of anicore that never existed, carried over unchanged from aniframe when the dependency was renamed.
The core data structures come from anicore, which is what the aniframe package was renamed to in its 0.8.0 (animovement/anicore#84). The aniframe class keeps its name; only the package providing it changed, so anicore replaces aniframe in Imports and in every aniframe:: call.

AGENTS.md is kept out of the built package, which R CMD check reported as a non-standard top-level file.
The confidence plot puts the finest-grained identity on its axis, whatever that column is called (#21). It previously looked for a column named keypoint and, failing that, fell back to the coarsest varying grouping column — the opposite of what the code’s own comment described. On a frame declaring identity as, say, animal and bodypart, the axis and the facets came out swapped, rendering without error but transposed. Frames using keypoint are unaffected.

The identity columns are read from the variables_what declaration that anicheck carries through to the check object. Check objects from an earlier anicheck carry no declaration; for those, keypoint remains the best guess available.

First substantial release of the plotting layer, built on aniframe (>= 0.6.0).

plot_trajectory() draws x/y paths with an adaptive colour scheme — hue per what, shade per when — a time legend, gap bridging, and start and end markers.
plot_timeseries() plots any per-frame numeric variable against time, inline or faceted.
plot_events() and plot.anievent(), with geom_event_state() and geom_event_point(), draw state and point events — ethograms and spike rasters — on an hms time axis.
Presentation methods for the check_*() objects produced by anicheck, dispatched via the anivis_check_* classes and staged by a shared as_plot_data() generic: plot.anivis_check_na_timing() for the distribution of missing values over time, plot.anivis_check_na_gapsize() for gap-size occurrence and totals, and plot.anivis_check_confidence() for per-keypoint tracking confidence as clipped horizontal violins.
theme_animovement(), in light and dark, and theme_imputets() for the check plots.
The Okabe-Ito and Material colour palettes with their scale_*() functions, and plots(), a patchwork wrapper.

Package skeleton. No user-facing functions yet — the plotting layer arrives in 0.2.0.
