In Accessing and Visualising Sentencing Data for Local Courts I posted a couple of quick ways in to playing with Ministry of Justice sentencing data for the period July 2010-June 2011 at the local court level. At the end of the post, I wondered about how to wrangle the data in R so that I [...]
A recent provisional data release from the Ministry of Justice contains sentencing data from English(?) courts, at the offence level, for the period July 2010-June 2011: “Published for the first time every sentence handed down at each court in the country between July 2010 and June 2011, along with the age and ethnicity of each [...]

Picking up on Paul Bradshaw’s post A quick exercise for aspiring data journalists which hints at how you can use Google Spreadsheets to grab – and explore – a mortality dataset highlighted by Ben Goldacre in DIY statistical analysis: experience the thrill of touching real data, I thought I’d describe a quick way of analysing [...]
I couldn’t contain myself (other more pressing things to do, but…), so I just took a quick time out and a coffee to put together a quick and dirty R function that will let me run queries over Google spreadsheet data sources and essentially treat them as database tables (e.g. Using Google Spreadsheets as a [...]
Another way for the database challenged (such as myself!) for merging two datasets that share at least one common column… This recipe using the cross-platform stats analysis package, R. I use R via the R-Studio client, which provides an IDE wrapper around the R environment. So for example, here’s how to merge a couple of [...]
