tidymodels Detect metrics
Detection commands
Find all metric definitions (recommended):
grep -E ".* <- new_.*_metric\(" R/*.R
Find available metric constructors:
grep -E "^new_.*_metric <- function" R/*.R
Check exported metrics:
grep "^export(" NAMESPACE | sed 's/export(//' | sed 's/)//'
Metric structure
Each metric has:
- Generic function calling
UseMethod() - Constructor wrap:
metric_name <- new_*_metric(metric_name, direction = "minimize"|"maximize"|"zero") - Data frame method using
*_metric_summarizer() - Vector implementation:
metric_name_vec()
