In ck37/ckTools: Chris Kennedy's R Toolkit

Table of PR-AUCs from SuperLearner result

Description

Calculates precision-recall AUC for each learner in the SuperLearner.

Usage

## S3 method for class 'SuperLearner'
prauc_table(x, y = x$Y, sort = TRUE, ...)

Arguments

x	SuperLearner object
y	Outcome vector, if not already added to SL object.
sort	Sort table by order of AUC.
...	Any additional unused arguments, due to the prauc_table generic.

Value

Dataframe table with PR-AUCs.
