title: 'cifmodeling: Visualization and Polytomous Modeling of Survival and Competing
  Risks'
version: 0.9.9
doi: 10.32614/CRAN.package.cifmodeling
abstract: 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'.
