What is radiatR?

A circular-statistics toolkit for animal movement, shipped and then tightened in three weeks.

radiatR reads movement trajectories, plots them on circular axes, computes kinematics such as speed and path sinuosity, and runs the circular statistics that go with them, including tests of mean direction, symmetry and unimodality. It arrived as a first public release on 9 July 2026 with an accompanying Shiny app, and has had two releases since at roughly weekly intervals. The 0.1.x line is still setting its boundaries: 0.1.2 removes a loader dialect and makes previously silent data problems into errors.

What is smam?

Animal-movement models in R, where new stochastic processes arrive years apart.

smam fits statistical models of animal movement, covering moving-resting processes with and without measurement error, moving-resting-handling, and moving-moving processes, with simulation, point estimation and variance estimation for each. The last three releases are pure upkeep: guarding Rf_error calls after an Rcpp update, a maintainer email change, and a compiler warning fix. The substantive work in this window is 0.7.0, which added estimate and vcov generics across all fit functions, and 0.6.0, which added the moving-moving process.

2.5

A circular-statistics toolkit for animal movement, shipped and then tightened in three weeks.

◆ Current state

radiatR reads movement trajectories, plots them on circular axes, computes kinematics such as speed and path sinuosity, and runs the circular statistics that go with them, including tests of mean direction, symmetry and unimodality. It arrived as a first public release on 9 July 2026 with an accompanying Shiny app, and has had two releases since at roughly weekly intervals. The 0.1.x line is still setting its boundaries: 0.1.2 removes a loader dialect and makes previously silent data problems into errors.

◆ Where it's heading

Three releases in twelve days show a package hardening in public rather than accreting features. The direction of travel is toward refusing bad input instead of quietly working around it: non-finite coordinate rows now error by default rather than being dropped silently, combining Tracks objects rejects colliding trajectory ids and conflicting calibration metadata instead of merging them and discarding one side, and the Shiny app clears prior state before reading a new upload. The statistical surface is growing in parallel, but within the scope the first release already claimed.

◆ Prediction

Expect the remaining goodness-of-fit gap the notes name explicitly, Jones-Pewsey, to be filled in a later release, and the error-on-bad-input treatment to reach the parts of the loader it has not yet covered. A CRAN submission is the natural next step for a package this young, though nothing in these entries commits to one.

0.0

Animal-movement models in R, where new stochastic processes arrive years apart.

◆ Current state

smam fits statistical models of animal movement, covering moving-resting processes with and without measurement error, moving-resting-handling, and moving-moving processes, with simulation, point estimation and variance estimation for each. The last three releases are pure upkeep: guarding Rf_error calls after an Rcpp update, a maintainer email change, and a compiler warning fix. The substantive work in this window is 0.7.0, which added estimate and vcov generics across all fit functions, and 0.6.0, which added the moving-moving process.

◆ Where it's heading

This package grows by adding process models, and it does so rarely. Between the moving-moving process in 2021 and now, the only interface-level change has been the 0.7.0 generics that gave every fit function a common way to retrieve estimates and their covariance, which is consolidation of an accumulated collection rather than expansion of it. The three releases since are entirely reactive to toolchain and CRAN pressure, and they arrive in step with the maintainer's other package coga, which received the same Rcpp guard within twenty minutes on the same day.

◆ Prediction

Expect further releases to be CRAN and Rcpp maintenance unless a new movement process is published, which is what has historically prompted a minor version here. The generics added in 0.7.0 give any future process model a ready-made interface to slot into.
