[R-pkgs] acs package version 1.1: download and analyze census data from the ACS
We are pleased to announce that version 1.1 of the acs package is now
available on CRAN. The package allows users to automatically
download, analyze, and present data from the U.S. Census American
Community Survey.
Major improvements in versions 1.0 and 1.1 include:
* A single "acs.fetch()" function allows users to downloading data
directly from the new Census American Community Survey API and
import it into R (with proper statistical treatment of estimates
and error, variable and geographic relabeling, and more);
* A new "geo.make()" function allows users to create their own
custom geographies from the existing census hierarchy to organize
and download data. The function accepts over 20 different
geographic options (state, county, tract, congressional district,
zip code, metropolitan statistical area, different types of state
school and legislative districts, and more), which may be set to
create and endlessly-combine 25 different summary levels for easy
downloading from the Census; and
* Two special lookup tools help users filter Census geographies
(with the "geo.lookup()" function) and statistical tables (with
the "acs.lookup()" function) to find exactly what they want.
The package is well documented via the manual on CRAN, as well as a
User Guide available at
<http://eglenn.scripts.mit.edu/citystate/wp-content/uploads/2013/06/wpid-working_with_acs_R3.pdf>.
Additional support, worked examples, and more can be found on the
CityState blog (<http://eglenn.scripts.mit.edu/citystate>), as well as
