ezr.plot_auc: AUC PLOT

In jmp1989/easyr: Helpful wrappers for common EDA, Data Manipulation, & Modeling

Description

Generates an AUC plot. Can compare two different fields against each other if needed. Can plot either FPR vs TPR columns or Truth vs prediction value(s). Adds the AUC alues to the plots.

Usage

ezr.plot_auc(dataset, fpr_or_truth, tpr_or_pred, pred_2nd_model = NULL,
  title = NULL, metrics_precalculated = FALSE, add_text = TRUE)

Arguments

dataset	dataset
fpr_or_truth	fpr value or truth. Default is expecting a 0/1 truth value.
tpr_or_pred	fpr or prediction value. Default expects a prediction value.
pred_2nd_model	Default is NULL. If you wish to compare two plots side-by-side, then you must use truth & prediction values.
title	plot title
metrics_precalculated	FALSE by default. This means expects a 0/1 truth_or_fpr and a score in the pred_or_tpr. Set to TRUE if you already know that the FPR and TPR are already calculated for you.
add_text	add text to plot? Default is true.

Value

Returns a plot of the AUC-values
