cofad vs tectonicr
A side-by-side editorial comparison of cofad and tectonicr — release velocity, themes, recent moves, and the top alternatives to consider.
cofad vs tectonicr: 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 tectonicr?
Stress-field analysis tracks the 2025 World Stress Map and keeps adding plotting shortcuts.
tectonicr analyses the orientation of maximum horizontal stress, comparing observed azimuths against those predicted by plate motion in a plate-of-rotation reference frame. Version 0.4.7 added support for the 2025 World Stress Map release and made the version selectable at download; 0.4.8 followed with new summary statistics for axial data, ggplot2 geoms for plotting directions, and a faster kappa estimator.

◆ 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.

0.0INFRA · APIS
Stress-field analysis tracks the 2025 World Stress Map and keeps adding plotting shortcuts.
◆ Current state
tectonicr analyses the orientation of maximum horizontal stress, comparing observed azimuths against those predicted by plate motion in a plate-of-rotation reference frame. Version 0.4.7 added support for the 2025 World Stress Map release and made the version selectable at download; 0.4.8 followed with new summary statistics for axial data, ggplot2 geoms for plotting directions, and a faster kappa estimator.
◆ Where it's heading
The package is maturing along two axes at once. On the statistics side the circular methods keep getting corrected and accelerated, with a major fix to est.kappa() for doubling angles before treating them as directional data and a faster approximation replacing the maximum likelihood path by default. On the usability side the additions are convenience wrappers, data2PoR() and the geom_azimuth pair, which is what a package does once its core methods stop moving. A sign convention for deviation was also flipped, which quietly changes existing results.
◆ Prediction
Expect the convenience layer to keep growing around a stable core, and the next substantive release to track whatever the World Stress Map publishes after 2025.

Frequently asked questions
What is the difference between cofad and tectonicr?
They serve adjacent needs but don't currently overlap on shipped themes. cofad and tectonicr are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Is cofad better than tectonicr?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. cofad and tectonicr are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
