R Open Labs: Loading Data

At last week’s R Open Lab, we explored two packages (Memisc and foreign) as well as some of R’s native commands for loading data files into our R Studio workspace.

I <3 R

 

 

 

 

 

 

 

 

We practiced with ASCII, .TSV, .SAV, and .DTA files, all available from ICPSR, a data archive with a rich collection of social science data sets.

We’re taking a break from  R Open Labs this week, but we’ll be back on February 17 at 10 am in the DSSC.

Share your thoughts and suggestions with us here, and we’ll see you next week!

 

R Open Lab: Week 1

I <3 R

Last week, we kicked off R Open Labs with a demo on Base Graphics, or how to make graphics using basic commands. We also gave a brief intro to Swirl, a great package for learning R.

You can catch up here with these helpful slides: Base Graphics System

Check back next week, Wednesday, Feb. 3 at 10 am, for a quick demo on how to load different data files into R, a free I <3 R button, and plenty of time to practice your code and ask questions.

Got feedback or want to suggest a package to demo? Leave a comment or take our short survey!

NHGIS Releases Standardized Tables for 2000 & 2010 Census

Comparing Census data from one decade the next can be difficult since boundaries  and variables can change. Trying to figure out those differences can be time consuming and sometimes frustrating. To help make this easier, NHGIS recently released 65 time series tables standardizing 2000 & 2010 100% count variables to the 2010 Census boundaries for ten geographic levels including tracts, block groups and 5 digit zip code tabulation areas (ZCTAs).

The tables are marked with a TS from within the Topic filter

NHGIS topic filter

Available standardized tables are listed in the Time Series Tables tab, and labeled Standardized to 2010 under the Geographic Integration column.

More information on time tables produced by the NHGIS can be found in the Data Documentation section, including both the geographically standardized tables as well as nominally integrated tables. The page includes methodology, and a PDF containing the complete list of variables within the time series datasets.
