Assign single ages to 5-year abridged age groups. That means that age 0 is kept as a single age, ages 1-4 are grouped together as abridged age 1, and thereafter 5-year age groups are used.

calcAgeAbr(Age)

## Arguments

Age integer. Vector of single ages (lower bound).

## Value

An integer vector of length(Age) indicating the abridged age group that each single age belongs to.

## Details

In the case that the single Age vector starts at some age higher than 4, this is just the same as calcAgeN(Age,5,0).

## Examples

Age <- 0:70
calcAgeAbr(Age)
