format_age_lifetab: Create consistent, complete life table age group

In johnrbryant/demprep: Prepare Demographic Data

Description

Given a vector of age group labels, create a factor that contains levels for all ages between 0 and break_max, plus an open age group (ie an age group with no upper limit.) The age groups created by format_age_lifetab are the ones typically used in "abridged" life tables: "0", "1-4", "5-9", "10-14", and so on up to the highest age group, which is always open.

Usage

format_age_lifetab(x, break_max = 100)

Arguments

x	A vector of age group labels.
break_max	An integer or NULL. Defaults to 100.

Details

break_max is used to specify the oldest age group. If break_max is NULL, the oldest age group is derived from the data.

All age groups in x must fall within the intervals "0", "1-4", "5-9", ....

If x contains NA, then the levels of the factor created by format_age_lifetab also contain NA.

Value

A factor with the same length as x.

• format_age_year

• format_age_multi

• format_age_births

Examples

format_age_lifetab(x = c("100+", "14", "1-4"))

## set oldest age group to 50+
format_age_lifetab(x = c("100+", "14", "1-4"),
                   break_max = 80)
