prostate

Anonymized data from a randomized clinical trial of prostate cancer published in Byer &amp; Green (1980).

datasets

A publication-ready toolkit for modern survival and competing risks
analysis with a minimal, formula-based interface. Both nonparametric
estimation and direct polytomous regression of cumulative incidence
functions (CIFs) are supported. The main functions 'cifcurve()', 'cifplot()',
and 'cifpanel()' estimate survival and CIF curves and produce high-quality
graphics with risk tables, censoring and competing-risk marks, and
multi-panel or inset layouts built on 'ggplot2' and 'ggsurvfit'. The modeling
function 'polyreg()' performs direct polytomous regression for coherent joint
modeling of all cause-specific CIFs to estimate risk ratios, odds ratios, or
subdistribution hazard ratios at user-specified time points. All core
functions adopt a formula-and-data syntax and return tidy and extensible
outputs that integrate smoothly with 'modelsummary', 'broom', and the broader
'tidyverse' ecosystem. Key numerical routines are implemented in C++ via
'Rcpp'.
