Although I have always wanted to add such feature to pander, a recent question on SO urged me to create some helper functions so that users could easily highlight some rows, columns or even just a few cells in a table and export the result to markdown,...

Massive online data stream mining with R
A few weeks ago, the stream package has been released on CRAN. It allows to do real time analytics on data streams. This can be very usefull if you are working with large datasets which are already hard to put in RAM completely, let alone to build some statistical model on it without getting into RAM problems.
Most of...
Review of Mathematica 9 and R-link
VIDEO TRANSCRIPT: Hello, this is Matt Asher from StatisticsBlog.com. I’m going to be reviewing Mathematica 9, from Wolfram Research. In particular, I’ll be focusing on using it with R and to do Monte Carlo simulations and other statistical work. You can find a full transcript of this video at my blog, including the source code
Happy St Patrick’s Day
I love Saint Patrick’s Day for, at least, two reasons. The first one is that, on March 17th, you can play out loud The Pogues, the second one is that it’s the only day in the year when I really enjoy getting a Guiness in a pub. And Guiness is important in statistical science (I did mention a couple...
Visualizing neural networks from the nnet package
Neural networks have received a lot of attention for their abilities to ‘learn’ relationships among variables. They represent an innovative technique for model fitting that doesn’t rely on conventional assumptions necessary for standard models and they can also quite effectively handle multivariate response data. A neural network model is very similar to a non-linear regression 
A Review of the R Graphics Cookbook
A common criticism of R, especially from data scientists who are new to R but proficient in multiple programming languages, is that R is “quirky” and annoying because there is almost always more than one way to do simple things. I usually counter that they are trying to say that R is “flexible” and “rich”, but by the time...
2011 Census Open Atlas Project
This month has seen the release of the 2011 census data for England and Wales at Output Area Level. This offers the possibility to map various attributes about people and places for very small geographic areas. Output Areas represent the most detailed geography for which Census data are released and are the building blocks for
Generating Labels for Supervised Text Classification using CAT and R
The explosion in the availability of text has opened new opportunities to exploit text as data for research. As Justin Grimmer and Brandon Stewart discuss in the above paper, there are a number of approaches to reducing human text to … Continue reading →
Tracking down errors in R
It's that moment we all know and love, somewhere in our code something has gone wrong. We think we have done everything right, but instead of expected glory we find only terse red text lain below our lintel.
This can be very frustrating, and trouble shooting these issues can often be very time consuming.
All is not lost. There are a...
European Migration
Last week on the radio I heard a story of southern Europeans and Irish looking for better times in northern Europe. I heard the tale of an Italian academic who left Italy to end up waiting tables in an Italian restaurant in the Netherlands. Obviously t...
