In epicentre-msf/llutils: Linelist Utilities

Description

Calculate age in years from dates of birth.

Usage

age_from_dob(dob, until = Sys.Date(), as_int = TRUE)

Arguments

dob	Vector of dates of birth. If not of class "Date", will attempt to convert using lubridate::as_date.
until	End-date used for age calculation. Defaults to current date (based on Sys.Date()). If not of class "Date", will attempt to convert using lubridate::as_date.
as_int	Logical indicating whether to return ages rounded down to the nearest integer (TRUE), or as numeric decimal values (FALSE). Defaults to TRUE.

Value

Vector of ages in units of years, either of class integer (if as_int = TRUE) or numeric (as_int = FALSE).

Examples

dates_of_birth <- as.Date(
  c("2001-04-05", "1976-10-24", "1990-03-15", "1943-12-08")
)

# by default returns integer ages
age_from_dob(dates_of_birth)

# use as_int = FALSE to return decimal values
age_from_dob(dates_of_birth, as_int = FALSE)

# calculate with end-point other than current date
age_from_dob(dates_of_birth, until = "2019-01-01")
