tinytigertinytiger is designed to be low dependency to allow
packages and newer R users to use TIGER lines and shapefiles without
accruing non-standard dependencies. It has four dependencies: -
sf, needed to work with shapefiles - curl,
needed for downloading the files from the Census Bureau -
cli, used to create clear errors, warnings, and messages. -
glue, used for constructing complex URLs and already a
dependency of cli
While cli is not necessary, it fits within our goals
that tinytiger to be friendly for package development and
new users, as cli is one of the most-widely downloaded R
packages and comes with but one dependency itself.
tinytigerlibrary(tinytiger)tinytiger has methods to download TIGER shapes for most
Census geographies. A full list are available on the tinytiger
website.
To download any shapes, we can use the corresponding function for the
geography. All functions are prefixed with tt_.
For counties, for example, we can run:
counties <- tt_counties()#> Error in curl::curl_download(url, path, quiet = quiet) : HTTP error 304.head(counties)Other options for downloads are:
