Figure Aesthetics or Overlays?

Tinkering with a new chart type over the weekend, I spotted something rather odd in in my F1 track history charts – what look to be outliers in the form of cars that hadn’t been lapped on that lap appearing behind the lap leader of the next lap, on track. If you count the number

Track Concordance Charts

Since getting started with generating templated R reports a few weeks ago, I’ve started spending the odd few minutes every race weekend around looking at ways of automating the generation of F1 qualifying and race reports. Im yesterday’s race, some of the commentary focussed on whether MAS had given BOT an “assist” in blocking VET,

Experimenting With Sankey Diagrams in R and Python

A couple of days ago, I spotted a post by Oli Hawkins on Visualising migration between the countries of the UK which linked to a Sankey diagram demo of Internal migration flows in the UK. One of the things that interests me about the Jupyter and RStudio centred reproducible research ecosystems is their support for

How Reproducible Data Analysis Scripts Can Help You Route Around Data Sharing Blockers

For aaaagggggggeeeeeeesssssss now, I’ve been wittering on about how just publishing “open data” is okay insofar as it goes, but it’s often not that helpful, or at least, not as useful as it could be. Yes, it’s a Good Thing when a dataset is published in support of a report; but have you ever tried

Reporting in a Repeatable, Parameterised, Transparent Way

Earlier this week, I spent a day chatting to folk from the House of Commons Library as a part of a bit of temporary day-a-week-or-so bit of work I’m doing with the Parliamentary Digital Service. During one of the conversations on matters loosely geodata-related with Carl Baker, Carl mentioned an NHS Digital data set describing

A Recipe for Automatically Going From Data to Text to Reveal.js Slides

Over the last few years, I’ve experimented on and off with various recipes for creating text reports from tabular data sets, (spreadsheet plugins are also starting to appear with a similar aim in mind). There are several issues associated with this, including: identifying what data or insight you want to report from your dataset; (automatically

Running the Numbers – How Can Hamilton Still Take the 2016 F1 Drivers’ Championship?

Way back in 2012, I posted a simple R script for trying to work out the finishing combinations in the last two races of that year’s F1 season for Fernando Alonso and Sebastien Vettel to explore the circumstances under which Alonso could take the championship (Paths to the F1 2012 Championship Based on How They

DH Box – Digital Humanities Virtual Workbench

As well as offering digital application shelves, should libraries offer, or act as instituional sponsors of, digital workbenches? I’ve previously blogged about things like SageMathCloud, and application based learning environment, and the IBM Data Scientist Workbench, and today came across another example: DHBox, CUNY’s digital humanities lab in the cloud (wiki), which looks like it

Using Docker as a Personal Productivity Tool – Running Command Line Apps Bundled in Docker Containers

With its focus on enterprise use, it’s probably with good reason that the Docker folk aren’t that interested in exploring the role that Docker may have to play as a technology that supports the execution of desktop applications, or at least, applications for desktop users. (The lack of significant love for Kitematic seems to be

First Thoughts on Detecting Motorsport Safety Car Periods from Laptimes

Prompted by Markku Hänninen, I thought I’d have a quick look at estimating motorsport safety car laps from a set of laptime data. For the uninitiated, if there is a dangerous hazard on track, the race-cars are kept out while the hazard is cleared, but led around by a safety car that limits the pace. No
