A side-by-side editorial comparison of admiral and ggsurvfit — release velocity, themes, recent moves, and the top alternatives to consider.
admiral vs ggsurvfit: at a glance
What is admiral?
admiral spent its last cycle making complex derivations documentable rather than adding more of them.
admiral is the pharmaverse's ADaM dataset derivation toolkit — a large library of derive_* functions for building analysis datasets from SDTM. The 1.2.0 and 1.3.0 releases added new derivation functions and then a substantial documentation overhaul: argument defaults now appear in the help text and complex functions carry titled, described examples. 1.3.1 was a hotfix for links and the search index.
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.

◆ Current state
admiral is the pharmaverse's ADaM dataset derivation toolkit — a large library of derive_* functions for building analysis datasets from SDTM. The 1.2.0 and 1.3.0 releases added new derivation functions and then a substantial documentation overhaul: argument defaults now appear in the help text and complex functions carry titled, described examples. 1.3.1 was a hotfix for links and the search index.
◆ Where it's heading
The direction is toward usability of an already-large API rather than growth of it. 1.1.0 rewrote error messaging to be user-facing, 1.2.0 added flexibility to duplicate handling across several functions via check_type, and 1.3.0 invested in the structured-example documentation that the rdx_roclet work in {admiraldev} made possible. The two packages move together.
◆ Prediction
With the documentation infrastructure in place, expect the remaining complex derivation functions to be brought up to the structured-example standard, and new therapeutic-area work to keep landing in the extension packages rather than the core.
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.
