Convert age in months to years;months

Usage

format_year_month_age(x)

Arguments

x: a vector ages in months

Value

ages in the years;months format

Details

Ages of NA return "NA;NA".

This format by default is not numerically ordered. This means that c("2;0", "10;10", "10;9") would sort as c("10;10", "10;9", "2;0"). The function stringr::str_sort(..., numeric = TRUE) will sort this vector correctly.

Examples

ages <- c(26, 58, 25, 67, 21, 59, 36, 43, 27, 49)
format_year_month_age(ages)
#>  [1] "2;2"  "4;10" "2;1"  "5;7"  "1;9"  "4;11" "3;0"  "3;7"  "2;3"  "4;1"
