A function to calculate ROC curve, calculate area under the curve (AUC), calculate the optimal threshold, plot the curve, and classify the peaks.

Description

A function to calculate ROC curve, calculate area under the curve (AUC), calculate the optimal threshold, plot the curve, and classify the peaks.

Usage

e_roc_gg(
  dat,
  var_class,
  val_feat,
  sw_plot = TRUE,
  method_name = "",
  sw_thresh_criteria = c("min_dist", "spec1_sensmax", "sens1_specmax")[1]
)

Arguments

dat	dataset name
var_class	true classification
val_feat	XXX DON'T REMEMBER
sw_plot	TRUE/FALSE switch to create plot or not
method_name	PREVIOUSLY USED FOR TITLE
sw_thresh_criteria	(min distand, max spec, or max sens)

Value

out is a list including the optimal threshold, val_feat (XXX), good_class (XXX), plot_roc is a plot of the roc curve using ggplot, and roc_dat includes the curve, best value of the curve, and cm.feat (XXX?)
