tigris | R Documentation |
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.
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.
Four options
control behavior of various tigris
functions.
