new-metric {yardstick} | R Documentation |
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.
