## How to: network animation with R and the iGraph package & Meaning in data viz

November 27, 2012
By

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

November 26, 2012
By

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

November 25, 2012
By

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

November 21, 2012
By

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

November 16, 2012
By

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

## Simulating Sudden Oak Death Dynamics

I am working on a project with the Rizzo Lab examining the dynamics of Sudden Oak Death (SOD). I really have to write more about this, but today I’m just going to post the results of an initial exercise.

Here I attempt to replicate model results from Cobb et al. (2012). The model in that paper simulates...

## Network vizualization and meaning shifting due to algorithm settings

November 15, 2012
By

Data visualizations are useful for exploratory work and as an aid in communicating findings. Data visualizations also seem to be in demand these days as a kind of eye candy for capturing attention. But when we look at one engaging enough to hold our attention, we want to know what it means. In other words,
