Generating Sankey Diagrams from rCharts

A couple of weeks or so ago, I picked up an inlink from an OCLC blog post about Visualizing Network Flows: Library Inter-lending.

Vectors of S4 classes with non-trivial slots

Here’s another rabbit hole where I spent a bit of time this evening. I like OOP and I like the way R uses vectors. I’ve created a few classes and had started to code a function which would plot a set of them. It all seemed straightforward until I realized that the infrastructure for treating

Bike sharing in 100 cities

Many cities around the world have bike sharing programs: pick up a bike at a docking station, ride it across town and drop it off at another session, and just pay for the time you use. (Even Albacete, the Spanish college down hosting last month's UseR conference, had one.) Most of these systems provide open data feeds of bike...

Do the Simpsons characters like each other?

One day, while I was walking around Cambridge, I had a random thought — how do the characters on the Simpsons feel about each other? It doesn’t take long to figure out how Homer feels about Flanders (hint: he doesn’t always like him), or how Burns feels about everyone, but how does Marge feel about Bart? ...

Le Monde puzzle [#825]

The current puzzle is the last one before the summer break and not exciting enough to take along: Take the first ten digits, create five pairs out of those, and for each pair (x,y) derive the quantity (min(x,y)+1.5max(x,y)). What is the collection of pairs that maximises the product of those quantities? I wrote the following
