Data Textualisation – Making Human Readable Sense of Data

A picture may be worth a thousand words, but whilst many of us may get a pre-attentive gut reaction reading from a data set visualised using a chart type we’re familiar with, how many of us actually take the time to read a chart thoroughly and maybe verbalise, even if only to ourselves, what the

Using R: Coloured sizeplot with ggplot2

Someone asked about this and I though the solution with ggplot2 was pretty neat. Imagine that you have a scatterplot with some points in the exact same coordinates, and to reduce overplotting you want to have the size of the dot indicating the number of data points that fall on it. At the same time

What makes us happy?  Lets look at data to find out.

I've had a lot of different jobs over the past 4 years, and I've had some incredible experiences along the way. Lately, I've been struggling with what to do next. Or perhaps more accurately, I've been struggling with how to decide what to do next. Decisions that seem obvious in hindsight are tough to come to grips with beforehand,...

Parallel R (and air travel)

Parallel R (and air travel)

My heart sinks a little when I check on my laptop in the morning and the computation I started the night before still hasn’t finished. Even when the data I’m playing with isn’t particularly.... large... (I’m not going to say it), I have a knack for choosing expensive algorithms late at night. Because of my »more

Animated Twitter Networks

In this blogpost I presented a visualization made with R that shows how almost the whole world expresses its attention to political crises abroad. Here’s another visualization with Tweets in October 2013 that referred to the Lampedusa tragedy in the Mediterranean. But this transnational public space isn’t quite as static as it

A slightly different introduction to R, part V: plotting and simulating linear models

In the last episode (which was quite some time ago) we looked into comparisons of means with linear models. This time, let’s visualise some linear models with ggplot2, and practice another useful R skill, namely how to simulate data from known models. While doing this, we’ll learn some more about the layered structure of a

Visualising Structure in Topic Models

How exactly should we visualise topic models to get an overview of how topics relate to each other? This post is a brief lit review of that debate - I realise the subject matter is sooo last year. I also present my chosen solution to the dilemma: I use dendrograms to position topic, and add a...
