\alias{age}
\title{Age in years of individuals}
\usage{
age(x, reference = Sys.Date())
age(x, reference = Sys.Date(), exact = FALSE)
}
\arguments{
\item{x}{date(s), will be coerced with \code{\link{as.POSIXlt}}}
\item{reference}{reference date(s) (defaults to today), will be coerced with \code{\link{as.POSIXlt}} and cannot be lower than \code{x}}
\item{exact}{a logical to indicate whether age calculation should be exact, i.e. with decimals}
}
\value{
Integer (no decimals)
An integer (no decimals) if \code{exact = FALSE}, a double (with decimals) otherwise
}
\description{
Calculates age in years based on a reference date, which is the sytem date at default.
