Twitter has become a powerful medium for organizing and communicating with factions during popular uprisings: the crisis in Egypt, the uprising in Syria, the revolution in Iran, and other conflicts all around the world. Twitter's effectiveness relies on its ability for the various factions to self-organize and to fight the information battle in social media. Esteban Moro Egido, a...

2012-11 Generating Animation Sequence Descriptions
This report describes the animaker package for generating descriptions of animation sequences. An animation sequence is composed by combining atomic animations in series to create sequence animations or in parallel to create track animations. Functions are provided for manipulating animation … Continue reading →
The tools in an R package developer’s toolbox
Yihui Xie is the creator of several popular R packages, including knitr, animation and cranvas. In an interview with The Setup, he shares some of the software and hardware he uses in his data-to-day work, including (of course) R: For programming and data analysis, I primarily use R since I'm a statistician. I have created a bunch of R...
How to: network animation with R and the iGraph package & Meaning in data viz
This article lists the steps I take to create a network animation in R, provides some example source code that you can copy and modify for your own work, and starts a discussion about programming and visualization as an interpretive approach in research. Before I start, take a look at this network animation created with
Applications open for 2013 John M Chambers Statistical Software Award
In 1998, John Chambers won the ACM Software Systems award for the S language, which the ACM heralded as having "forever altered how people analyze, visualize, and manipulate data". The R language is "not unlike S", and John continues pushing the frontiers of statistical computing as a member of the R Core Group. Ang his legacy continues in another...
Fast Conway’s game of life in R
Here I demonstrate a simple way to code Conway's game of life (GoL) in R and to produce the animation above. Cellular automata in R are usually painfully slow if you iterate through all grid cells in an array. A … Continue reading →
Successive Differences of a Randomly-Generated Timeseries
I was wondering about the null distribution of successive differences of random sequences, and decided to do some numerical experiments. I quickly realized that successive differences equates to taking successively higher-order numerical derivatives, ...
Fun with coin flips
We all know that the odds of flipping an unbiased coin is 50% heads, 50% tails. But what happens if you do this a lot of times. Do you expect the same number of heads and tails? What if we took a cumulative sum where heads = +1 and tails = -1. What wou...

The Race to the F1 2012 Drivers’ Championship – Initial Sketches
In part inspired by the chart described in The electoral map sans the map, I thought I’d start mulling over a quick sketch showing the race to the 2012 Formula One Drivers’ Championship. The chart needs to show tension somehow, so in this first really quick and simple rough sketch, you really do have to
