Guerrill-R, get it? Register now for the Guerrilla Data Analysis Techniques (GDAT) class to be held during the week of August 9-13, 2010. The focus will be on using R and the PDQ-R for computer performance analysis and capacity planning.(Click on the...
Copy and paste the code listed in this post below, and you can create a plot of World Bank data using R with a call like the following:plotWorldBank('USA','NY.GDP.MKTP.KD.ZG')There is a wealth of economic and demographic available at the World Bank. ...
Early this morning I sent Rcpp version 0.8.1 off to CRAN and Debian. In the meantime, Romain has already provided a very nice blog post about it. There are a few fairly visible new things in this release. As we want to focus the next few minor release...

I was recently asked to review a soon to be published book on PostGIS, a spatial extension to the very popular Postgresql relational database. I was very excited about receiving an early copy of this book, as the authors have provided countless tips, ...
R did definitely not start to be THE statistical computing tool. The “two Rs” in far down-under just needed some tool which was not too expensive and structured enough to support the elementary statistics classes filled with hundreds of students. Another constraint was the computing lab which was large enough, but “only” filled with Mac
Revolution's CEO Norman Nie recently gave an interview to CNET's Dave Rosenberg, who blogs on disrupting the software market. Among the topics covered: What is R (Nie: "R is the most powerful statistical computing language on the planet"), what is predictive analytics ("statistical modeling by another name") and plans for Revolution R ("we intend to bring predictive analytics to...
We released Rcpp 0.8.0 almost a month ago. It finalized our efforts in designing a better, faster and more natural API than any version of Rcpp ever before. The journey from Rcpp 0.7.0 to
Imprtent update to the post (17.07.10) I now came across David smith’s post on the REvolution blog, pointing to instruction on the R wiki for how to install R on the iPhone! I didn’t try it myself since it both requires jailbreaking the iPhone, and I don’t have an iPhone. But it is still interesting to know of. Preface...
Probably the question I get asked the most about R is, "What is R"? It's can be a hard question to answer, because R is so many things. It's data analysis software. It's an environment for data analysis. It's a language. It's an open-source project. It's a community. The Wikipedia page for R does a great job of describing...
As you probably figured out, I am an Amazon affiliate and have been giving some thought to how to get the best lists of R books available at Amazon. To get the list of ISBNs from R-Project, the following Ruby script did the trick:require 'rubygems'req...
In our previous entry, we described how to calculate the Nelson-Aalen estimate of cumulative hazard. In this entry, we display the estimates for the time to linkage to primary care for both the treatment and control groups in the HELP study.RWe use the...
I recently have done some empirical studies on zero-coupon bond modelling and pricing, and plan to create an interest rate R package in order to make it re-usable, as I find there are only two R package on it, one is http://cran.r-project.org/web/pack...

As promised a few posts ago, another demonstration of the excellent biomaRt package, this time in conjunction with GenomeGraphs. Here’s what we’re going to do: Grab some public microarray data Normalise and get a list of the most differentially-expressed probesets Use biomaRt to fetch the genes associated with those probesets Plot the data using GenomeGraphs

Christopher has the RPMs (for Fedora users) for JAGS, coda, and rjags on his blog. The specific blog entry is here: http://cddesjardins.wordpress.com/2010/06/04/jags-package-for-fedora-13-64-bit/ If you have trouble installing JAGS or rjags in Fedora,...

Continuing in the context of this previous post… 1. Select a static symbol from the R sources, like Connections $ grep "static Rconnection Connections" src/main/connections.c static Rconnection Connections; 2. Get its address $ objdump -t `R RHOME`/bin/exec/R | awk '/ Connections/ {print $1}' 000000000093b700 3. Use the symbol > library(inline) > code <- " +

Another unashamedly subjective book review - but first a little more about my history as it relates to R...A few years ago, I was doing some systems administration work at an industrial company for whom IT was a cost center. I wanted to illustrate to...
There are a huge number of plots, annotations and parameters available in R for constructing charts and graphics. While looking through the R Programming wikibook I noticed a reference to a library called playwith. It provides a GUI that allows you ...
In connection with the Valencia 9 meeting that started yesterday, and with Hedie‘s talk there, we have posted on arXiv a set of comments on particle learning. The arXiv paper contains several discussions but they mostly focus on the inevitable degeneracy that accompanies particle systems. When Lopes et al. state that is not of interest

When you upload a video to YouTube, they don't store a perfect digital copy of your media file. The video is actually re-encoded into the MPEG-4 video format. This saves space on YouTube's servers, but also introduces some random degradation to the video (as a result of the lossy compression process). So what happens if you then save that...
