admiraldiscovery vs ggsurvfit
A side-by-side editorial comparison of admiraldiscovery and ggsurvfit — release velocity, themes, recent moves, and the top alternatives to consider.
admiraldiscovery vs ggsurvfit: at a glance
What is admiraldiscovery?
A lookup index for the admiral family that grows one therapeutic area at a time.
admiraldiscovery is a search aid rather than a code package: it maps ADaM variables to the {admiral} functions that derive them, alongside a listing of conference presentations. Its releases are catalogue updates, not functional changes. The most recent adds variables from {admiralneuro} plus AAGE and NFRLT.
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.

admiraldiscovery
0.0ANALYTICS
A lookup index for the admiral family that grows one therapeutic area at a time.
◆ Current state
admiraldiscovery is a search aid rather than a code package: it maps ADaM variables to the {admiral} functions that derive them, alongside a listing of conference presentations. Its releases are catalogue updates, not functional changes. The most recent adds variables from {admiralneuro} plus AAGE and NFRLT.
◆ Where it's heading
Each release absorbs the variable listing of whichever therapeutic-area extension shipped most recently — paediatrics in 0.3.0, metabolic in 0.4.0, neuro in 0.6.0. The package is effectively an index trailing the family's expansion, so its cadence is a proxy for how fast new admiral extensions appear.
◆ Prediction
The next release will most likely fold in variables from whichever admiral therapeutic-area package lands next, together with a refreshed presentation list.
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.
