A new version of the acs package is now on CRAN. I recommend that all users of choroplethr update to this version. Here is how to do it:



[1] ‘2.1.1’

As a reminder, after updating the acs package you might need to reinstall your Census API key with ?api.key.install.

New Performance Issue

Internally, choroplethr uses the acs package to fetch demographic data from the Census Bureau’s API. Unfortunately, this version of the acs package introduces a performance issue (and solution) when fetching data. Here is an example of the problem:


time_demographic_get = function()
    start.time = Sys.time()
    df = get_state_demographics()
    end.time = Sys.time()
    end.time - start.time

time_demographic_get() # 1.9 minutes

Performance Issue Fix

The fix for this performance issue is simply to call the function ?acs.tables.install. You only need to call this function once. Doing so will dramatically speed up the performance of choroplethr’s various “get_*_demographics” functions:


time_demographic_get() # 9.4 seconds

A big thank you to Ezra Haber Glenn, the author of the acs package, for his continued work maintaining the package.
