Create labels for age groups. The labels depend
on the type argument:
"single". One-year age groups, eg
"0" or "55", and possibly
an open age group, eg "90+".
"five". Five-year age groups, eg
"0-4" or "55-59", and possibly
an open age group, eg "100+".
"lt". Life table age groups, eg
"0", "1-4", "5-9",
"55-59", or "80+".
Usage
age_labels(type, min = 0, max = 100, open = NULL)
Value
A character vector.
Arguments
type
Type of age group labels:
"single", "five", or "lt".
min
Minimum age. Defaults to 0.
max
Maximum age for closed age groups.
Defaults to 100.
open
Whether the last age group is
"open", ie has no upper limit.
Details
The first age group starts at the age
specified by min. If open is TRUE,
then the final age group starts at the age
specified by max. Otherwise, the
final age group ends at the age specified
by max.
open defaults to TRUE when
min equals zero, and to FALSE
otherwise.
