tinytiger
tinytiger
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.
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:
