[R] Calculation of Age heaping

According to Wikipedia, this is the definition of Whipple's index:

"The index score is obtained by summing the number of persons in the
age range 23 and 62 inclusive, who report ages ending in 0 and 5,
dividing that sum by the total population between ages 23 and 62 years
inclusive, and multiplying the result by 5. Restated as a percentage,
index scores range between 100 (no preference for ages ending in 0 and
5) and 500 (all people reporting ages ending in 0 and 5)."

Let ages be a vector of integers representing ages.
whipple <- function (ages) {
    mids <- ages[ages >= 23 & ages <= 62] * 2
    5 * mean( mids %% 10 == 0)
}

If you want any other digit(s), you could try
whipple <- function (ages, digits = c(0,5)) {
    mids <- ages[ages >= 23 & ages <= 62] %% 10
    (10/leng(digits)) * mean(mids %in% digits)
}

So it is not clear to me why you want any package to do this.
The Whipple index does not come with any statistical measure of strength,
although https://en.wikipedia.org/wiki/Whipple%27s_index
mentions a UN table of values to compare with.

That Wikipedia page also warns about limits to applicability.
I note that with the exception of using an upper inclusive bound of
62 (as in the Wikipedia page) this definition of the Whipple index
agrees perfectly with that in A'Hearn et al's papers (which use 72)
but NOT with DemoTools.  So you need to be very clear to yourself
and others where your definition of the Whipple index comes from,
what it is, and whether the code you use computes what you think
it does.  (UNTESTED CODE ABOVE!)
