Aggregate Indicator Scores

Description

Computes summary scores from an evidence table, grouped by one or more columns.

Usage

aggregate_indicator_score(
  ev,
  by = "indicator_id",
  method = c("mean", "min", "weighted")
)

Arguments

ev	A valid evidence data.frame.
by	Character vector of column names to group by. Default: c("indicator_id").
method	Aggregation method: "mean", "min", or "weighted". The "weighted" method uses severity_to_weight() and result_to_score().

Value

A data.frame with grouping columns plus score (0–1) and n_evidence (count of rows).

Examples

ctx <- suppressMessages(r4sub_run_context("STUDY1", "DEV"))
ev <- suppressMessages(as_evidence(
  data.frame(
    asset_type = rep("validation", 3), asset_id = rep("ADSL", 3),
    source_name = rep("pinnacle21", 3),
    indicator_id = c("SD0001", "SD0001", "SD0002"),
    indicator_name = c("SD0001", "SD0001", "SD0002"),
    indicator_domain = rep("quality", 3),
    severity = c("high", "medium", "low"),
    result = c("fail", "warn", "pass"),
    stringsAsFactors = FALSE
  ),
  ctx = ctx
))
aggregate_indicator_score(ev, by = "indicator_id", method = "weighted")
