Description
To obtain variable codes and other metadata needed to
access the Census API, both acs.fetch and acs.lookup
must consult various XML lookup files, which are provided by the
Census with each data release. To keep the acs package-size small, as
of version 2.0 these files are accessed online at run-time for each
query. As an alternative, users may use acs.tables.install to
download and archive all current tables (approximately 10MB, as of
version 2.0 release).
Use of this function is completely optional and the package should
work fine without it (assuming the computer is online and is able to
access the lookup tables), but running it once may result in faster
searches and quicker downloads for all subsequent sessions. (The
results are saved and archived, so once a user has run the function,
it is unnecessary to run again, unless the acs package is re-installed
or updated.)
Usage
1
Value
Downloads the files and saves them to the package's "extdata"
directory; return an error if no files found.
