animovement vs hydroloom: at a glance
What is animovement?
animovement stopped being a package and became a metapackage over seven focused ones.
animovement handles animal movement data — tracking output from pose-estimation and centroid trackers, cleaned into a standard form. Its 0.7.3 release, the first GitHub tag since November 2024, bundles the 0.5 through 0.7 development series and records a structural change: the codebase was split into aniframe, aniread, aniprocess, anicheck, animetric, anivis and anispace, which animovement now bundles and re-exports. The package has done this before at smaller scale, having renamed itself from trackballr in 0.2.0 to match a widened scope.
What is hydroloom?
USGS puts a type system over its river network toolkit so errors surface at dispatch
hydroloom builds and navigates hydrologic flow networks, carrying functionality migrated out of nhdplusTools. Version 1.2.0 introduces an S3 class hierarchy — hy_topo, hy_leveled, hy_node, hy_flownetwork — assigned automatically by hy() and by producer functions, letting the package validate input at dispatch time and emit guided errors. Outlet detection is now defined explicitly: a row is an outlet when its toid is not in id, with reserved values, NA and implicit absence all accepted.

animovement stopped being a package and became a metapackage over seven focused ones.
◆ Current state
animovement handles animal movement data — tracking output from pose-estimation and centroid trackers, cleaned into a standard form. Its 0.7.3 release, the first GitHub tag since November 2024, bundles the 0.5 through 0.7 development series and records a structural change: the codebase was split into aniframe, aniread, aniprocess, anicheck, animetric, anivis and anispace, which animovement now bundles and re-exports. The package has done this before at smaller scale, having renamed itself from trackballr in 0.2.0 to match a widened scope.
◆ Where it's heading
Development has moved to the constituent packages, which release far more often than animovement itself — aniframe, aniread and aniprocess have each shipped multiple times in 2026 while animovement tagged once. That makes animovement a stable install surface rather than where the work happens, and the ani_df data class plus the frame-rate to sampling-rate terminology change are the contracts holding the suite together. Optional dependencies are handled through animovement_install_suggested() against r-universe and Bioconductor mirrors.
◆ Prediction
With the split done and the constituent packages iterating independently, animovement releases are likely to become periodic roll-ups of the suite rather than carriers of new functionality.

USGS puts a type system over its river network toolkit so errors surface at dispatch
◆ Current state
hydroloom builds and navigates hydrologic flow networks, carrying functionality migrated out of nhdplusTools. Version 1.2.0 introduces an S3 class hierarchy — hy_topo, hy_leveled, hy_node, hy_flownetwork — assigned automatically by hy() and by producer functions, letting the package validate input at dispatch time and emit guided errors. Outlet detection is now defined explicitly: a row is an outlet when its toid is not in id, with reserved values, NA and implicit absence all accepted.
◆ Where it's heading
The package spent its first releases porting and broadening — non-dendritic network support, divergence routing, subsetting that follows diversions out of a basin — and has now turned to making that surface safe to use. The class hierarchy is the structural expression of that turn: instead of every function re-checking whether a data frame has the columns it needs, the type carries the guarantee. The explicit outlet rule resolves a category of failure where valid networks errored on NA or orphan toid values.
◆ Prediction
The release notes flag that subclass attributes are stripped by standard dplyr operations, which is the kind of rough edge that usually generates follow-up work — expect attribute preservation or restoration helpers next.
