Valentine Day and lonely people in France

Insee published recently a paper (in French), well in line with the Valentine Day, which characterizes people living alone or in couple by socio-professional category, along with the data. Between 1990 and 2008 (two population surveys), the proportion of people living alone mostly increased for people under 60. After 60, 38% of women live alone,Continue reading “Valentine Day and lonely people in France”

It is based on shapefile files, for example the ones offered by the French geography agency IGN (at départements and communes level). Some additional material like roads and railways are provided by the OpenStreetMap project, here. For the above map, you needContinue reading “Create maps with maptools R package”

Google Fusion Tables

A quick post about another Google service that I discovered recently called Fusion Tables. There you can store, share and visualize data up to 250 MB, of course in the cloud. With Google Docs, Google Trends and Google Public Data Explore, it is another example of Google’s efforts to gain ground in data management. HasContinue reading “Google Fusion Tables”

Triathlon data with ggplot2

As Jérôme and I like so much to play with triathlon data, it is a pleasure to see that we are not alone. Christophe Ladroue, from the university of Bristol, wrote this post yesterday: An exercise in plyr and ggplot2 using triathlon results, followed by part II, way better than ours, here and here.

Power of running world records

Following a few entries on sports here and there, I was wondering what kind of law follow the running records with respect to the distance. The data are available on Wikipedia, or here for a tidied version. It collects 18 distances, from 100 meters to 100 kilometers. A log-log scale is in order: It isContinue reading “Power of running world records”

Random Colours (part 2)

In this previous post, Julyan presented the paintings of Gerhard Richter, and asked whether the colours were really “randomly chosen”, as claimed by the painter. To answer the question from a statistical point of view (ie whether the colours are uniformly distributed in the (r,g,b) space or in the (x, y, r, g, b) spaceContinue reading “Random Colours (part 2)”
