Create a Threshold Metric — metric

Wraps a metric to return TRUE/FALSE based on a threshold. Logical, numeric, feedback, and trace-aware metrics all use the package-wide metric protocol; feedback and trace dispatch are preserved by the wrapper.

Usage

metric_threshold(metric, threshold = 0.5, comparison = ">=")

Arguments

metric: A metric function returning a logical/numeric score or list(score = , feedback = ).
threshold: The threshold value for success
comparison: One of ">=", ">", "==", "<", "<="

Value

A metric function returning logical scores. Trace-aware and feedback protocols are preserved when present on metric.

Examples

# F1 score with threshold
metric <- metric_threshold(metric_f1(), threshold = 0.8)
metric("the quick brown fox", "the fast brown fox")  # FALSE (0.75 < 0.8)
#> [1] FALSE
