In gsClusterDetect: Utilities for Geo-Spatial Cluster Detection and Significance Classification

Generate Census Tract Centroids for a State

Description

Pulls census tracts using tigris, computes tract centroids, and returns a three-column data.table with GEOID, latitude, and longitude.

Usage

tract_generator(st, county = NULL, use_cache = TRUE, ...)

Arguments

st	Character scalar; either a 2-digit state FIPS code (for example, "24") or a 2-letter USPS abbreviation (for example, "MD").
county	A three-digit FIPS code (string) of the county or counties to subset on. This can also be a county name or vector of names.
use_cache	a boolean, defaults to TRUE, to set tigris option to use cache
...	arguments to be passed on to tigris::tracts()

Value

A data.table with columns:

geoid

11-digit tract GEOID (state(2) + county(3) + tract(6))

latitude

Centroid latitude in WGS84

longitude

Centroid longitude in WGS84

Examples

md_tracts <- tract_generator("24")
md_tracts2 <- tract_generator("MD")
howard_county_tracts <- tract_generator("MD", county = "027")
head(md_tracts)
