In London Olympics 2012 Medal Tables At A Glance? I posted some treemap visualisations of the Olympics medal tables generated using a Google Visualisation Chart treemap component. I thought it might be worth posting a quick R generated example too, using the off-the-shelf/straight out of CRAN treemap component. (If you ... [Read more...]

Earlier this year I doodled a recipe for comparing the folk commonly followed by users of a couple of BBC programme hashtags (Social Media Interest Maps of Newsnight and BBCQT Twitterers). Prompted in part by a tweet from Michael Smethurst/@fantasticlife about generating an ESP map for UK politicians (something ... [Read more...]

multiplicitiesoffreedom demonstrates Chaos Theory in Excel. If he filled in more initial values, you would see a thick bar—like a picture of white-noise. Butterflies flapping their wings in Vermont to change the wind in Hangzhou? A drop of water on ... [Read more...]

Why don’t X-Y plots of latitude and longitude data look “right” compared to traditional map views? For example, here’s an X-Y scatterplot of some of Jenson Button’s McLaren telemetry data from the 2010 Australian Formula One Grand Prix: The image was generated, from a data file hosted on ...

What’s the potential audience size around a Twitter hashtag? Way back when, in the early days of webs stats, reported figures tended to centre around the notion of hits, the number of calls made to a server via website activity. I forget the details, but the metric was presumably ... [Read more...]

I think one of valid criticisms around a lot of the visualisations I post here and on my various #f1datajunkie blogs is that I often don’t post any explanatory context around the visualisations. This is partly a result of the way I use my blog posts in a ... [Read more...]

Looking over the sector times from the qualifying session for tomorrow’s Hungarian Grand Prix, I noticed that Vettel was only fastest in one of the sectors. Whilst looking for an easy way of shaping an R data frame so that I could plot categorical values sector1, sector2, sector3 on ... [Read more...]

The release of the R package “googleVis” has made the production of interactive maps through Google’s Chart Tools a simple task. Ignoring the some basic data manipulation the below map... [Read more...]

A recent question over at BioStar asked whether abstracts returned from a PubMed search could easily be visualised as “word clouds”, using Wordle. This got me thinking about ways to solve the problem using R. Here’s my first attempt, which demonstrates some functions from the RCurl and XML packages. ... [Read more...]

***This tutorial has been updated, please click here*** I frequently use R (a free software environment for statistical computing and graphics) for data analysis.  As almost all my data are spatial it is often good to produce a map of the results without having to export the data into another ...
