Convert Age Break String to Age Group Labels

Converts a semicolon-separated string of numeric age breakpoints into a character vector of age group labels. For example, the input `"0;5;10;...;80;Inf"` will produce the labels `"0–4"`, `"5–9"`, ..., `"80+"`.

Usage

age_breaks_to_labels(age_string)

Arguments

age_string

A single character string of age breakpoints, separated by semicolons. Must include at least two breakpoints. The last breakpoint can be `Inf` to indicate an open-ended upper age group.

Value

A character vector of formatted age group labels.

age_breaks_to_labels("0;5;10;15;20;25;30;35;40;45;50;55;60;65;70;75;80;Inf")
