[R] [R-pkgs] acs version 2.1.0 update: download and analyze data from the US Census in R
We are pleased to announce the release of version 2.1.0 of the "acs" package, now available on CRAN <http://cran.r-project.org/web/packages/acs/index.html>. The package allows users to download, manipulate, analyze, and present demographic data from the U.S. Census, with special tools and methods to simplify the tasks of working with estimates and standard errors contained in data from the American Community Survey (ACS). Important: version 2.1.0 of the package is a "minor update" in terms of features, but it includes a number of low-level tweaks necessary to accommodate upcoming changes in the Census API, including a shift to https transfer. Current users are strongly encouraged to update as soon as possible to avoid problems at the end of the summer. Other minor changes include (a) removing plyr from a "dependency" and simply importing the required "rbind.fill" function, and (b) updating cbind/rbind options to be consistent with S3 methods.

[R] [R-pkgs] acs version 2.0: an R package to download and analyze data from the US Census
We are pleased to announce the release of version 2.0 of the "acs" package, now available on CRAN <http://cran.r-project.org/web/packages/acs/index.html>. The package allows users to download, manipulate, analyze, and present demographic data from the U.S. Census, with special tools and methods to simplify the tasks of working with estimates and standard errors contained in data from the American Community Survey (ACS). Version 2.0 of the package provides full support for all ACS data available through the Census API -- including the most recent 2014 data -- as well as Decennial Census Data from 1990, 2000, and 2010. Users can work with existing census geographies (states, counties, tracts, block-groups, places, zip code areas, congressional districts, school districts, etc.), or create and save their own custom geographies with the package's "geo.make()" function. For more information please visit: <http://eglenn.scripts.mit.edu/citystate/2016/03/acs-version-2-0-now-on-cran>, and the newly-updated "Working with acs.R" user guide at <http://dusp.mit.edu/sites/dusp.mit.edu/files/attachments/publications/working_with_acs_R_v_2.0.pdf>. Special thanks to package beta testers (Ari, Arin, Bethany, Emma, John, and Michael) and the entire acs-r community, as well as to Uwe and Kurt at CRAN for their infinite patience and continuing care and stewardship of the system. -- Ezra Haber Glenn, AICP Department of Urban Studies and Planning Massachusetts Institute of Technology 77 Massachusetts Ave., Room 7-337 Cambridge, MA 02139 egl...@mit.edu http://dusp.mit.edu/faculty/ezra-glenn | http://eglenn.scripts.mit.edu/citystate/ 617.253.2024 (w) 617.721.7131 (c) ___ R-packages mailing list r-packa...@r-project.org https://stat.ethz.ch/mailman/listinfo/r-packages __ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
[R] [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 through the acs.R user group mailing list -- visit <http://mailman.mit.edu/mailman/listinfo/acs-r> to subscribe and view archives. -- Ezra Haber Glenn, AICP Department of Urban Studies and Planning Massachusetts Institute of Technology 77 Massachusetts Ave., Room 7-337 Cambridge, MA 02139 egl...@mit.edu http://dusp.mit.edu/faculty/ezra-glenn | http://eglenn.scripts.mit.edu/citystate/ 617.253.2024 (w) 617.721.7131 (c) ___ R-packages mailing list r-packa...@r-project.org https://stat.ethz.ch/mailman/listinfo/r-packages __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
[R] [R-pkgs] acs package: analyze data from the U.S. American Community Survey
We are pleased to announce version 0.8 of the acs package for R, now available on CRAN (<http://cran.r-project.org/web/packages/acs/index.html>. The package provides a general toolkit for managing, analyzing, and presenting data from the U.S. Census American Community Survey (ACS). Confidence intervals provided with the data are converted to standard errors and bundled with estimates in complex "acs-class" objects. The package provides new methods to conduct standard operations, plots, and tests on acs objects in statistically appropriate ways. In addition to improved documentation and bug-fixes, highlights include: * An improved "read.acs" function for importing data downloaded from the Census American FactFinder site. * "rbind" and "cbind" functions to help create larger acs objects from smaller ones. * A "sum" method to aggregate rows or columns of ACS data, dealing correctly with both estimates and standard errors. * A new "apply" method to allow users to apply virtually any function to each row or column of an acs data object. * A snazzy new "plot" method capable of plotting both density plots (for estimates of a single geography and variable) and multiple estimates with errors bars (for estimates of the same variable over multiple geographies, or vice versa). * New functions two deal with adjusting the nominal values of currency from different years for the purpose of comparing between one survey and another. * A new prompt method to serve as a helper function when changing geographic rownames or variable column names.
