Plots an ROC model — pROC_quick

Quickly plots a model based on my own liking

Usage

pROC_quick_plot(
  mod,
  thres_method = c("youden", "closest.topleft"),
  col = "blue",
  ...,
  boots = 0L
)

Arguments

mod: An object with class "roc" (a ROC model made with [pROC::roc()])
thres_method: The threshold method to print
col: The color of the curve
...: Additional arguments passed to [pROC::plot.roc()]
boots: Number of bootstrap replications to perform; if < 2L will not perform any

Details

When adding bootstrapped confidence intervals, the core function of `pROC:::ci.sp.roc()` is replaced with a quicker version that uses parallel processing to speed up the bootstraps and some other data manipulation. There will likely be a delay when running with bootstraps.

Examples

if (mark::package_available("pROC")) {
  x <- pROC::aSAH
  mod <- pROC::roc(x$outcome, x$s100b, levels = c("Good", "Poor"))
  pROC_quick_plot(mod)
if (FALSE) {
  pROC_quick_plot(mod, boots = 100)
}
}
