new-metric: Construct a new metric function

In yardstick: Tidy Characterizations of Model Performance

Construct a new metric function

Description

These functions provide convenient wrappers to create the three types of metric functions in yardstick: numeric metrics, class metrics, and class probability metrics. They add a metric-specific class to fn and attach a direction attribute. These features are used by metric_set() and by tune when model tuning.

See Custom performance metrics for more information about creating custom metrics.

Usage

new_class_metric(fn, direction)

new_prob_metric(fn, direction)

new_numeric_metric(fn, direction)

new_dynamic_survival_metric(fn, direction)

new_integrated_survival_metric(fn, direction)

new_static_survival_metric(fn, direction)

Arguments

fn	A function. The metric function to attach a metric-specific class and direction attribute to.
direction	A string. One of: "maximize" "minimize" "zero"
