plot_mean_roc: Plot ROC and PRC curves

Description

Plot ROC and PRC curves

Usage

plot_mean_roc(dat, ribbon_fill = "#C6DBEF", line_color = "#08306B")
plot_mean_prc(
  dat,
  baseline_precision = NULL,
  ycol = mean_precision,
  ribbon_fill = "#C7E9C0",
  line_color = "#00441B"
)

Arguments

dat

sensitivity, specificity, and precision data calculated by calc_mean_roc()

ribbon_fill

ribbon fill color (default: "#D9D9D9")

line_color

line color (default: "#000000")

baseline_precision

baseline precision from calc_baseline_precision()

ycol

column for the y axis (Default: mean_precision)

Functions

• plot_mean_roc(): Plot mean sensitivity over specificity

• plot_mean_prc(): Plot mean precision over recall
