Following on from A Tool Chain for Plotting Twitter Archive Retweet Graphs – Py, R, Gephi, here’s a quick view summary view over #UKGC12 tweets saved in Google Spreadsheet archive as developed by Martin Hawksey, generated from an R script (R code available here; #ukgc12 tweet archive here)… (I did mean to tidy these up, 
One of the great things about (software) code is that people build on it and out from it… Which means that as well as producing ever more complex bits of software, tools also get produced over time that make it easier to do things that were once hard to do, or required expensive commercial software 
Tomorrow, we will discuss Fisher-Tippett theorem. The idea is that there are only three possible limiting distributions for normalized versions of the maxima of i.i.d. samples . For bounded distribution, consider e.g. the uniform distribution on t...
So if you’re in need of deploying that nifty Rook app you made, download the latest release 0.1-3 on my github account or wait for it to appear on CRAN. That is all.
I’m feeling chancy, just like those two angels who took a chance on me so many years ago… So I decided to release rApache 1.1.15. You can grab the source from rapache.net. Notable change includes support for deploying Rook applications, which you
I love board games. Over the holidays, I came across this interesting post over at Arthur Charpentier’s Freakonometrics blog about the classic game of snakes and ladders. The post is a nice little demonstration of how the game can be formulated completely as a Markov chain, and can be analysed simply using the mathematics of 
Things have been a little quiet, post wise here, of late, in part because of the holiday season… but I have been posting notes on a couple of charts in progress over on the F1DataJunkie blog. Here are links to the posts in chronological order – they capture the evolution of the chart design(s) to 
The R package dcemriS4 provides routines for the quantitative analysis of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI), along with quantification of diffusion-weighted MRI (ADC = apparent diffusion coefficient) and quantitative T2 map...
Those of you following my occasional updates here know that I have previously posted code for graphing Twitter friend/follower networks using R (post #1. post #2). Kai Heinrich was kind enough to send me some updated code for doing so using a newer version of the extremely useful twitteR package. His very crisp, yet thoroughly
Another set of stepping stones that provide a clunky route to a solution that @mhawksey has been working on a far more elegant expression of (eg Free the tweets! Export TwapperKeeper archives using Google Spreadsheet and Twitter: How to archive event hashtags and create an interactive visualization of the conversation)… The recipe is as follows: 
Zero Inflated Models and Generalized Linear Mixed Models with R.
