collapse_ages function

Collapse upper ages into a single age group. Counts are summed while rates are recomputed where possible.

collapse_ages(.data, max_age = 100)

Arguments

• .data: A vital object including an age variable
• max_age: Maximum age to include in the collapsed age group.

Returns

A vital object with the same variables as .data, but with the upper ages collapsed into a single age group.

Details

If the object includes deaths, population and mortality rates, then deaths and population are summed and mortality rates are recomputed as deaths/population. But if the object contains mortality rates but not deaths and population, then the last rate remains unchanged (and a warning is generated).

Examples

aus_mortality |>
 dplyr::filter(State == "Victoria", Sex == "female") |>
 collapse_ages(max_age = 85)
