In ejanalysis/ejanalysis: Tools for Environmental Justice (EJ) Analysis

Get Census tract FIPS from block or block group FIPS

Description

Extract partial FIPS code from longer FIPS code

Usage

get.fips.tract(fips, clean = TRUE)

Arguments

fips	Vector of one or more elements, character class, 11, 12 or 15 characters long after missing leading zeroes inferred (tract, block group or block), required.
clean	Does not use clean.fips() if FALSE, which helps if the countiesall or other list is not yet updated, for example and lacks some new FIPS code

Details

For information on FIPS codes, see http://www.census.gov/geo/reference/ansi.html, and also see https://www.census.gov/geo/reference/geoidentifiers.html It does not check to see if the codes are valid other than counting how many characters each has.

Value

Returns a vector of one or more character elements, same lengths as fips. NA where input cannot be converted to tract/block group/block length code, as with county or state fips as input.
