Risk Equivalence Table

Source: R/risk_equivalence.R
risk_equivalence.Rd

Compares a reference activity to all other activities by computing the ratio of micromorts. "How many X-rays equal one skydive?"

Usage

risk_equivalence(reference, risks = NULL, min_ratio = 0.01, max_ratio = Inf)

Arguments

reference

Character. Activity name to use as the reference (denominator). Must match an activity value in risks.

risks

A tibble with at least activity and micromorts columns. Defaults to common_risks().

min_ratio

Numeric. Minimum ratio to include (default 0.01).

max_ratio

Numeric. Maximum ratio to include (default Inf).

Value

A tibble with columns: activity, micromorts, reference, reference_micromorts, ratio, equivalence.
