Get Everything Set Up I’m going to assume that you have access to a machine that will run JAGS. If you don’t, then you should be able to use WinBUGS, which is very easy to get set up. Unfortunately, the details of what follows may not help you as much if you’re using WinBUGS. To
Last year there were over 2,600 murders in Ciudad Juarez, and if the more than 1,800 murders so far this year are any indications, there will be even more murders in 2010. Ciudad Juarez is a scary place, but it wasn't always that way...

One of the R language's most powerful features is its ability to deal with random distributions: not just generating random numbers from various distributions (based on a very powerful pseudo-random number generator), but also calculating densities, probabilities, and quintiles. John Cook provides a handy reference chart listing all of the distributions supported by standard R (reproduced below -- and...
I just uploaded GillespieSSA 0.5-4 to CRAN. It should be just a matter of days before it has propagated itself across all mirrors. This release consists of minor revisions with no (intended) changes in functionality. The main change (and it is … Continue reading →
Auto-completion is fancy in a text editor. Notepad++ does not support auto-completion for the R language, so I spent a couple of hours on creating such an XML file to support R: Put it under ‘plugins/APIs‘ in the installation directory of Notepad++ (you can see several other XML files there supporting different languages such as
The proto package is my latest favourite R goodie. It brings prototype-based programming to the R language - a style of programming that lets you do many of the things you can do with classes, but with a lot less up-front work. Louis Kates and Thomas P...
The proto package is my latest favourite R goodie.

Louis Kates and Thomas Petzoldt provide an excellent introduction to using proto in the
