multi_ggroc: Plot multiple ROC curves

Description

Given a list of results computed by calculate_roc, plot the curve using ggplot and sensible defaults

Usage

multi_ggroc(datalist, fpf_string = rep("FPF", length(datalist)),
  tpf_string = rep("TPF", length(datalist)), lty = 1:length(datalist),
  label = NULL, label.adj.x = rep(0, length(datalist)),
  label.adj.y = rep(0, length(datalist)), label.angle = rep(45,
  length(datalist)))

Arguments

datalist

List of data frames as returned by calculate_roc

fpf_string

Column names identifying false positive fraction

tpf_string

Column names identifying true positive fraction

lty

Line types to distinguish curves

label

Optional vector of direct labels for the ROC curve, same length as datalist

label.adj.x

Adjustment for the positioning of the label, same length as datalist

label.adj.y

Adjustment for the positioning of the label, same length as datalist

label.angle

Adjustment for angle of label, same length as datalist

Value

• A ggplot object
