A couple hours work and we now have animations of the global anomalies: Created with the animation package in R. The code examples were a bit terse about some of the details but after fiddling about I was able to get the program to output an Html animation complete with java based playback controls. Write 
Here are some tips to speedup matrix computation in R. The author did not provide any benchmark though.

Last week I was shown the results of a workplace happiness questionnaire. The plots were ripe for a makeover. Most obviously, the pointless 3D effect needs removing, and the colour scheme is badly chosen.
I’ve just released two new packages for R: log4r and SortableHTMLTables. log4r is a minimal logging utility for R that’s inspired by the log4j family of logging tools. It has substantially fewer features than other logging tools for R, but it’s hopefully easier to use. SortableHTMLTables uses brew and the jQuery Tablesorter plugin to provide
Code will be in the drop box in a bit, once I shower: This is a wholesale replacement of previous versions, completely rewritten in raster. It will be the base going forward. All of the analysis routines will be rewritten using raster. For time series functionality I will continue to use zoo as that 
In the world of data preparation a common task is to identify duplicate records in a file or data set. A few years ago, I did most development work in Java, and shudder to think of the amount of code required to accomplish this sort of task. &nbs...

This video brings flashbacks for my days as a statistics consultant to a medical school. Some days we just weren't speaking the same language... (With thanks to reader MK for the tip: "It's funny because it is true...".)
From guest blogger Joseph Rickert. Last night I went to hear Ken Krugler of Bixolabs talk about Hadoop at the monthly meeting of the Software Developers Forum. Maybe because Ken is an unusually lucid speaker, or maybe because I just reached some sort of cumulative tipping point through the prep work of all those patient people who have tried...
