plotROC

Description

This function plots a ROC curve with ggplot2.

Usage

plotROC2(
  x,
  ...,
  ylab = "Sensitivity (TPR)",
  xlab = if (legacy.axes) "1-Specificity (FPR)" else "Specificity (FPR)",
  main = NULL,
  lwd = 1.1,
  size = lwd,
  col = NULL,
  colour = if (is.null(col)) "gray50" else col,
  include.facet_wrap = FALSE,
  legend.position = "bottom",
  include.labels = TRUE,
  include.table = FALSE,
  include.order = TRUE,
  caption = "Optimal cut-point: Area Under the Curve (AUC), Youden Index (YI).",
  legacy.axes = TRUE,
  ann.segment = if (legacy.axes) c(0, 1, 0, 1) else c(0, 1, 1, 0)
)

Arguments
