In case you missed them, here are some articles from last month of particular interest to R users. This post linked to slides and video from a 30-minute "Introduction to R" talk I gave on January 28, with links to many useful R resources. This post brought news that R's creators Robert Gentleman and Ross Ihaka have jointly won...

Crayola crayon colors, 1949-present

Here's an example I featured in my list of 7 Awesome Things about R (awesome thing #3: graphics and data visualization). The Learning R blog features a reproduction of a graphic that recently appeared on Flowing Data. It shows the colors in a box of Crayola crayons: before 1949 there were only 8, but over the years additional colors...

From the “blogosphere”? Hardly.

I generally skip over “From the Blogosphere”, a (mostly) weekly-summary of one or two blog posts in Nature’s “Authors” section (here is the latest). Why? Well, I’ve always suspected that the title is rather misleading. Now, I have the hard numbers to prove it. My feed reader contains an archive of 128 articles, dating back

How to combine Google maps and data in R

Every good artist needs a canvas, and when it comes to displaying geographic data placing those data in context -- on a map -- makes all the difference. A new package for R from Markus Loecher, RgoogleMaps, allows you to download a street or satellite map from Google simply by specifying the bounding latitude/longitude coordinates. (You need to sign...

Mapping the Massachusetts election upset with R

The blog Offensive Politics has done some in-depth analysis of the recent Senate special-election upset in Massachusetts, comparing the results of victorious Republican candidate Scott Brown to those of the unsuccessful Republican Presidential candidate John McCain in 2008. It's pretty clear that Brown out-performed expectations with Democratic voters, but this chart of the change in Democratic voters from 2008...

rgdal and other GIS-related packages for Mac OS X

CRAN contains ready-made binary packages for nearly all of its packages, but rgdal is one which I keep finding myself trying to install from source whenever I upgrade R. Compiled versions of rgdal, along with prerequisites and complements like the GDAL framework, GRASS, and even the old FFTW3 can be found at KyngChaos’s Wiki: http://www.kyngchaos.com/software/frameworks

What to Expect?

In 2007, I was introduced to Twitter via the written qualifying exam towards my Ph.D.. At first, I did not know what to do with it. After a good year or so (maybe even sooner) passed, I began to follow some very interesting people that share the same interests as me. It has transformed my academic experience. It is...

Introduce your friends to R

January 19, 2010

R has gotten quite a lot of exposure recently. It started with the feature article in the New York Times last January, but since then there's been a steady flow of articles about R in analyst reports, on blogs, in YouTube videos, on Twitter, as well as in the general news media. As a result, a lot of new...

Connecting to a DB2 database from R

Unlike RMySQL and RSQLite there is no RDB2. However, I found it pretty straightforward connecting to a DB2 database using the JDBC driver and the RJDBC package. For all this to work, DB2 should be setup to use TCPIP, which is not used by default. You need to set the DB2COMM DB2 environment variable to

A tale of two visualizations (because it’s Friday)

GEEK FIGHT!!! says JD Long on Twitter as the New York Times publishes a widely-reposted interactive graphic about Netflix rental data, and the Wall Street Journal also gets into the interactive-viz game with a graphic on bank bonuses. If it's a fight, it's a knockout in the first round, if you ask me. There's no surprise why the Netflix...
