Download and use U.S. Census TIGER shapefiles in R

Description

tigris is an R package that allows users to directly download and use TIGER/Line and cartographic boundary shapefiles from the US Census Bureau in R. For an overview of the package, visit its repository at https://github.com/walkerke/tigris or read Chapter 5 of the book Analyzing US Census Data: Methods, Maps, and Models in R at https://walker-data.com/census-r/census-geographic-data-and-applications-in-r.html.

Details

Use option tigris_use_cache to tell tigris to cache Census shapefile downloads. This is FALSE by default. e.g. options(tigris_use_cache=TRUE)

Use option tigris_refresh to force a refresh of cached tigris Shapefiles. e.g. options(tigris_refresh=TRUE)

Use option tigris_year to change the year for which you'd like to download data. e.g. options(tigris_year = 2017). The default year for the package is 2022.

Use option tigris_class to specify the class of spatial object you'd like returned. The default is "sf" for simple features objects. If you'd like a legacy object of class Spatial*DataFrame, use options(tigris_class = "sp"). Please note that legacy sp objects are no longer formally supported in tigris.

Note

Four options control behavior of various tigris functions. See Details for more information.
