cofad vs Fiscal: 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 Fiscal?
UK income tax calculations reach CRAN, then go quiet behind pointer-only release notes.
Fiscal computes UK income tax. It reached its 1.0.0 milestone in March 2026 and shipped two patch releases in the fortnight after, then stopped. The GitHub release bodies carry no changelog of their own: each one points at the NEWS file and the CRAN page, so the feed shows cadence but not content.

◆ 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.

UK income tax calculations reach CRAN, then go quiet behind pointer-only release notes.
◆ Current state
Fiscal computes UK income tax. It reached its 1.0.0 milestone in March 2026 and shipped two patch releases in the fortnight after, then stopped. The GitHub release bodies carry no changelog of their own: each one points at the NEWS file and the CRAN page, so the feed shows cadence but not content.
◆ Where it's heading
Three releases in a fifteen-day window reads as post-publication cleanup rather than a development push, which is the normal shape after a first CRAN acceptance. Because every body is the same boilerplate, direction has to be read from the tags alone, and the tags say only that two patches followed the 1.0.0 line.
◆ Prediction
The most likely next release is an annual one tracking a new UK tax year's rates and thresholds. The release notes as published give no evidence for anything beyond that.
