Usage
codes(state, district = c())Arguments
- state
The state(s) for which to obtain a code(s). Can be entered as either a state abbreviation or full name (case-insensitive).
`state` can be entered as either a single state or a vector of states. If `state` is a vector, `district` must be omitted.
- district
The county for which to obtain a code. Can be entered with or without "district" (case-insensitive).
Value
The code(s) of given state or district.
If only states are entered, a vector of length equal to the number of states is returned. If any states are not found or are invalid, `NA` is returned in their place.
If a state and district are entered, a single value with the code for the given district is returned. If the district is invalid for the given state, an error is thrown.
If both `state` and `district` are omitted, the entire list of available codes are returned, sorted by the state's abbreviation.
