postcode2ste {healthyAddress}

In what states do postcodes lie?

Description

While for most postcodes, the state enclosing it is easy to evaluate (e.g. most postcodes in 2000-2999 are in NSW), the general case is non-trivial. In particular, some postcodes straddle state borders.

Usage

postcode2ste(Postcodes, result = c("integer", "character"))

Arguments

Postcodes

An integer vector of postcodes.

result

One of "integer" or "character". If "character" the abbreviated state names(s) are returned.

Value

A vector, the minimal states that cover all postcodes given. For example, if all postcodes lie within a single state a scalar integer/string of that state is returned.

Examples

vic_poa <- c(3021L, 3084L, 3013L, 3147L, 3030L,
             3123L, 3070L, 3004L, 3250L, 3630L)

postcode2ste(vic_poa)
postcode2ste(vic_poa, result = "character")
postcode2ste(c(vic_poa, 2000L))
postcode2ste(3644L)
