epiparameter vs ggsurvfit
A side-by-side editorial comparison of epiparameter and ggsurvfit — release velocity, themes, recent moves, and the top alternatives to consider.
epiparameter vs ggsurvfit: at a glance
What is epiparameter?
epiparameter split its parameter library out of the package — and relicensed what remained.
epiparameter provides classes and methods for working with epidemiological parameter distributions — delays, offspring distributions, incubation periods — drawn from the published literature. As of 0.4.0 the library itself no longer lives here: the parameters moved to {epiparameterDB}, taken on as a dependency, leaving {epiparameter} as the code layer alone. The most recent release is a CRAN-driven patch.
What is ggsurvfit?
ggsurvfit is in correctness-and-compatibility mode, not feature mode.
The package draws survival and cumulative-incidence curves on a ggplot2 grammar, with risk tables, p-values and quantile annotations. Recent releases are entirely fixes and upstream tracking: ggplot2 v4.0.0 compatibility in 2025, and a 2026 patch correcting a Gray-test p-value that could be reported for the wrong competing event.

epiparameter split its parameter library out of the package — and relicensed what remained.
◆ Current state
epiparameter provides classes and methods for working with epidemiological parameter distributions — delays, offspring distributions, incubation periods — drawn from the published literature. As of 0.4.0 the library itself no longer lives here: the parameters moved to {epiparameterDB}, taken on as a dependency, leaving {epiparameter} as the code layer alone. The most recent release is a CRAN-driven patch.
◆ Where it's heading
Each release has clarified the boundary between the data and the tools that operate on it. 0.2.0 added coercion from {epireview} tables, 0.3.0 rewrote the classes and renamed much of the API, and 0.4.0 completed the separation while adding caching so loading the library stays cheap. Breaking changes have been frequent and deliberate rather than incidental.
◆ Prediction
With code and data separated, the two can version independently — expect parameter additions to appear in {epiparameterDB} releases while this package's changes stay focused on classes and methods.
ggsurvfit
2.5ANALYTICS
ggsurvfit is in correctness-and-compatibility mode, not feature mode.
◆ Current state
The package draws survival and cumulative-incidence curves on a ggplot2 grammar, with risk tables, p-values and quantile annotations. Recent releases are entirely fixes and upstream tracking: ggplot2 v4.0.0 compatibility in 2025, and a 2026 patch correcting a Gray-test p-value that could be reported for the wrong competing event.
◆ Where it's heading
The feature surface settled around 1.0.0, when risk-table alignment was exported and colour and linetype defaults became configurable. Since then the work is keeping pace with survival, ggplot2 and tidycmprsk changes, and closing cases where the plotted curve and the annotation disagreed — the p-value matched by position rather than name, confidence limits swapped for multi-state models, quantiles read off a plateau.
◆ Prediction
Expect the next release to track upstream survival or ggplot2 changes rather than add plotting features; the CDISC censoring convention adopted in Surv_CNSR() suggests further alignment with clinical data standards is the likelier direction.

logrx
A clinical-script logger that stopped shipping after its 0.2 line, changelogs made of merged PRs.
lobstr
R's object inspector is losing its view of the internals as CRAN closes off the private C API.

A weather-station data client that broke one return type to hand back distances instead of bare IDs.
giscoR
giscoR's 1.0 moved its dataset index into the cache, so new Eurostat releases arrive without a package update.
