Plot survival ROC curves — plot_surv

Generate ROC plots for a single timepoint for timeROC::timeROC() objects or for multiple timepoints.

plot_surv_roc(
  x,
  timepoint,
  col = setNames(palette.colors(length(x)), names(x)),
  lty = setNames(rep.int(1, length(x)), names(x)),
  main = paste0("ROC at day ", timepoint),
  xlab = "1 - Specificity",
  ylab = "Sensitivity",
  legend = TRUE
)

plot_surv_roc_trend(
  x,
  col = setNames(palette.colors(length(x)), names(x)),
  lty = setNames(rep.int(1, length(x)), names(x)),
  main = "AUROC over time",
  xlab = "time t",
  ylab = "AUC (t)"
)
