tigris is an R package that allows users to directly download and use TIGER/Line shapefiles (https://www.census.gov/geo/maps-data/data/tiger-line.html) from the US Census Bureau.
To install the package from CRAN, issue the following command in R:
install.packages('tigris')
Or, get the development version from GitHub:
devtools::install_github('walkerke/tigris')
As of version 0.9.1, tigris defaults to the 2018 TIGER/Line and Cartographic Boundary shapefiles.
To learn how to use the package, I'd recommend the following materials:
- My article in The R Journal, "tigris: An R Package to Access and Work with Geographic Data from the US Census Bureau"
- A webinar I gave with Ari Lamstein on tigris in April 2017
Available datasets:
Please note: cartographic boundary files in tigris are not available for 2011 and 2012, and have not yet been released for 2019.
