In my previous post on The network structure of CRAN I demonstrated how to use page rank and communities to visualize the structure of a graph.

Creating an email course for my R packages has significantly increased the number of people who use the packages. It has also reduced the learning curve for the packages and brought me into greater contact with my users. In this post I will share the 5 steps I took to create my course Learn to Map Census Data in R.

EMC recently ran a competion to find out why John McGuinness, the legendary motorcycle racer known as the "Morecambe Missile", is outperforms the average motorcycle racer. To answer this question, EMC instrumented his bike and his suit with a number of real-time sensors. (Data collected included gear and RPM for the bike, and heart rate and acceleration for the rider.) They did the same for Adam Child, a motorcycle racing journalist who acted as a "control" in this study.

In case you missed them, here are some articles from June of particular interest to R users.

The R Consortium, a trade group dedicated to the support and growth of the R Community, has launched with the R Foundation, Microsoft, RStudio and others as founding members.

My experience of UseR!2015 drew to an end shortly after I gave a Kaleidoscope presentation discussing "The Network Structure of CRAN".

In case you missed the news last week, the R Consortium was announced. This new non-profit trade group will work with the R Foundation to support the R Community and the R Project generally.

As you might expect, the announcement generated quite a bit of news in the press. Here are links to some of the coverage:

Here's a quick quiz: what rule is behind the number sequence: 2, 4, 8? This New York Times interactive lets you try to solve the puzzle yourself, and you can also see members of the public try to solve the problem in the Veritasium video below.
