This is (roughly) the lightning talk I gave in useR2011. If you are a reader of R-bloggers.com then this talk is not likely to tell you anything new. However, if you have a friend, college or student who is a new useRs of R, this talk will offer him a decent introduction to what the R blogosphere is all about.
The talk is a call for people of the R community to participate more in reading, writing and interacting with blogs.
Today I was informed of (what I believe is) a better the best WordPress plugin for R syntax highlighting called WP-CodeBox. This plugin doesn’t require any hacks to make it work (as opposed to the WP-Syntax plugin, which I wrote about in the past). WP-CodeBox can be downloaded and installed on a WordPress by searching for it in the “Add New” section in the plugins menu.
WP-CodeBox provides some nice features (some AJAX based) to the display of the code in the post:
The code box in the post can now be folded (top right of the code box) so the code can be hidden so to not clutter the post (if the code is too long)
The code box is added with another button (top left of the code box) which allows the reader to see the code in a new window – so to easily enable a copy paste of the code.
The options of the plugin allows automatic row numbering of the code, control over “tab” length and some other features.
An easily phrased (and solved?) Le Monde mathematical puzzle that does not [really] require an R code: The five triplets A,B,C,D,E are such that and Given that find the five triplets. Adding up both sets of equations shows everything solely depends upon E1… So running an R code that checks for all possible values of […]
A few months ago I did a mini project using open crime data and R to create crime visualisations. At that time, I was already thinking about a web app using Shiny but I couldn't justify the time to develop the app and then set up a server etc. Not unti...
A fishR user asked me if I had Weisberg Linear Growth Model (LGM) vignette. In the past, the Weisberg LGM referred to the fixed-effects models described in Weisberg (1993) and implemented in software that was written in XLISP-STAT and distributed … Continue reading →

Most books that discuss regression modeling start out and often finish with Ordinary Least Squares (OLS) as the technique to use; Generalized Least Squares (GLS) sometimes get a mention near the back. This is all well and good if the readers’ data has the characteristics required for OLS to be an applicable technique. A lot […]
The biggest German railway company, the 'Deutsche Bahn', is subject of frequent emotional discussions about being late all the time. A big German newspaper, the Süddeutsche Zeitung built the so-called 'train monitor' (Zugmonitor). The data is (or was) made available in cooperation with OpenDataCity: http://www.opendatacity.de/zugmonitor-a […]
Today I want to share the test and implementation for the Fast Threshold Clustering Algorithm (FTCA) created by David Varadi. This implementation was developed and contributed by Pierre Chretien, I only made minor updates. Let’s first replicate the results from the Fast Threshold Clustering Algorithm (FTCA) post: The clusters are stable and match David’s res […]
