Detect metrics

Detection commands

Find all metric definitions (recommended):

bash
grep -E ".* <- new_.*_metric\(" R/*.R

Find available metric constructors:

bash
grep -E "^new_.*_metric <- function" R/*.R

Check exported metrics:

bash
grep "^export(" NAMESPACE | sed 's/export(//' | sed 's/)//'

Metric structure

Each metric has:

  1. •Generic function calling UseMethod()
  2. •Constructor wrap: metric_name <- new_*_metric(metric_name, direction = "minimize"|"maximize"|"zero")
  3. •Data frame method using *_metric_summarizer()
  4. •Vector implementation: metric_name_vec()
