cofad vs rvMF
A side-by-side editorial comparison of cofad and rvMF — release velocity, themes, recent moves, and the top alternatives to consider.
cofad vs rvMF: at a glance
What is cofad?
Contrast analysis with a Shiny front end, shipping about one release a year
cofad performs contrast analyses for factorial designs in both between- and within-subject forms, and ships a Shiny GUI alongside the R interface. The 0.3.0 release in 2024 was the substantial one: a helper for calculating differences between two sets of lambdas for competing contrast analysis, improved summary output, removal of the plyr dependency, a rebuilt Shiny interface using standard elements after the sortable drag-and-drop proved unstable, and a change of maintainer to Johannes Titz. The most recent release is a one-line patch fixing degrees of freedom in the t-test table.
What is rvMF?
A fast von Mises-Fisher sampler that ships a citation more often than a feature.
rvMF generates pseudo-random vectors from the von Mises-Fisher distribution, the standard model for directional data on a sphere. Its released surface has not changed materially in the window: the three most recent tags cover a dropped dependency, a citation update, and a C++ linking correction. The February 2026 release removes the scModels import.

◆ Current state
cofad performs contrast analyses for factorial designs in both between- and within-subject forms, and ships a Shiny GUI alongside the R interface. The 0.3.0 release in 2024 was the substantial one: a helper for calculating differences between two sets of lambdas for competing contrast analysis, improved summary output, removal of the plyr dependency, a rebuilt Shiny interface using standard elements after the sortable drag-and-drop proved unstable, and a change of maintainer to Johannes Titz. The most recent release is a one-line patch fixing degrees of freedom in the t-test table.
◆ Where it's heading
Development is slow and correctness-led. The record runs from a JOSS publication in 2021 through a near three-year gap to a release that both extended the method and repaired the GUI, then a degrees-of-freedom fix. Maintainer and author order changed in 0.3.0, which typically marks a handover rather than a burst of new work, and the cadence since is consistent with that.
◆ Prediction
Expect low-frequency correctness releases; the competing contrast analysis helper added in 0.3.0 is the most likely thing to be extended if anything is.
rvMF
0.0INFRA · APIS
A fast von Mises-Fisher sampler that ships a citation more often than a feature.
◆ Current state
rvMF generates pseudo-random vectors from the von Mises-Fisher distribution, the standard model for directional data on a sphere. Its released surface has not changed materially in the window: the three most recent tags cover a dropped dependency, a citation update, and a C++ linking correction. The February 2026 release removes the scModels import.
◆ Where it's heading
This is a single-purpose sampler that reached its intended scope early and has been maintained rather than extended since. The visible work is dependency reduction and paper-and-citation housekeeping, which is the normal shape for a method package whose implementation is described in a published paper and whose correctness argument lives there rather than in the changelog.
◆ Prediction
More of the same: occasional releases to keep the C++ layer building and the dependency list short. Nothing in the notes points toward new distributions or new sampling methods.
