logrx vs mlr3cmprsk
A side-by-side editorial comparison of logrx and mlr3cmprsk — release velocity, themes, recent moves, and the top alternatives to consider.
logrx vs mlr3cmprsk: at a glance
What is logrx?
A clinical-script logger that stopped shipping after its 0.2 line, changelogs made of merged PRs.
logrx produces execution logs for R scripts in regulated clinical work, recording what ran, what it returned, and which unapproved packages or functions were used. Its release notes are raw merged-PR lists rather than written changelogs, which makes the substance hard to read from the feed. The most recent release, 0.2.2 in June 2023, exists to track tidyselect and dplyr changes.
What is mlr3cmprsk?
Competing risks arrive in mlr3, going from a non-parametric baseline to Fine-Gray regression in seven weeks.
mlr3cmprsk extends mlr3 to competing-risks analysis: learners predicting cumulative incidence functions, plus measures to score them. It appeared in February 2026 and reached 0.0.5 by April, adding a Fine-Gray learner and a Brier score along the way. The version numbers say pre-release; the cadence says active build-out.

◆ Current state
logrx produces execution logs for R scripts in regulated clinical work, recording what ran, what it returned, and which unapproved packages or functions were used. Its release notes are raw merged-PR lists rather than written changelogs, which makes the substance hard to read from the feed. The most recent release, 0.2.2 in June 2023, exists to track tidyselect and dplyr changes.
◆ Where it's heading
Feature work concentrated in the 0.1 line — return codes, a results writer, a to_report parameter, and logging of unapproved package and function use — and the 0.2 releases have been compatibility maintenance and hotfixes. Three years of silence in a pharmaverse that has otherwise kept shipping suggests the package reached the shape its users needed rather than that it was abandoned mid-design.
◆ Prediction
Nothing in these entries points to planned work; the likeliest trigger for a release is a breaking change in tidyverse dependencies, which is what produced the last one.
mlr3cmprsk
0.0ANALYTICS
Competing risks arrive in mlr3, going from a non-parametric baseline to Fine-Gray regression in seven weeks.
◆ Current state
mlr3cmprsk extends mlr3 to competing-risks analysis: learners predicting cumulative incidence functions, plus measures to score them. It appeared in February 2026 and reached 0.0.5 by April, adding a Fine-Gray learner and a Brier score along the way. The version numbers say pre-release; the cadence says active build-out.
◆ Where it's heading
The package assembled a working evaluation stack fast. It started with the Aalen-Johansen estimator as a non-parametric baseline, added Fine-Gray as a regression alternative, then filled in the scoring side with an AUC refactor and a fixed-time Brier score. Development has run in lockstep with survdistr and mlr3extralearners, which picked up the dependency at 1.5.2.
◆ Prediction
The visible gaps are more learners — cause-specific Cox and boosting variants — and the tuning and pipeline integration the rest of mlr3 expects; the measure side currently looks further along than the model side.

Frequently asked questions
What is the difference between logrx and mlr3cmprsk?
They serve adjacent needs but don't currently overlap on shipped themes. logrx and mlr3cmprsk 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 logrx better than mlr3cmprsk?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. logrx and mlr3cmprsk are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
