checkmate vs cofad
A side-by-side editorial comparison of checkmate and cofad — release velocity, themes, recent moves, and the top alternatives to consider.
checkmate vs cofad: at a glance
What is checkmate?
Infrastructure so widely depended on that its most consequential release changed nothing.
checkmate provides fast argument checks and is a dependency deep in the R package graph, which shapes everything about how it releases. The last five tags are small: a deprecated-internal-call cleanup, a complex-number edge case in allMissing(), a sprintf format fix. The most recent release removes calls to internal R functions that newer R versions no longer expose.
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.

Infrastructure so widely depended on that its most consequential release changed nothing.
◆ Current state
checkmate provides fast argument checks and is a dependency deep in the R package graph, which shapes everything about how it releases. The last five tags are small: a deprecated-internal-call cleanup, a complex-number edge case in allMissing(), a sprintf format fix. The most recent release removes calls to internal R functions that newer R versions no longer expose.
◆ Where it's heading
The package is in the phase where its obligations outweigh its ambitions. When R-devel changed whether NULL counts as atomic, checkmate's published response was to keep the old behaviour specifically to avoid breaking reverse dependencies, which is the clearest statement of its position in the stack. New check functions still appear, but rarely, and the bulk of the work is tracking upstream R and its C API.
◆ Prediction
Expect continued adaptation to R internals as the C API narrows, and any behaviour change to arrive with an explicit reverse-dependency justification rather than as a default flip.

Contrast analysis with a Shiny front end, shipping about one release a year
◆ 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.
