We all know that R can do amazing things including 3 dimensional plots. scatterplot3d is probably the most popular package for doing this. But a few days ago I got introduced with rgl package which can do 3 dimensional graphs with some added advantages like we can rotate the plot using mouse, zoom in or out using the mouse...

Animated Heatmap of WikiLeaks Report Intensity in Afghanistan
Visualisation of Activity in Afghanistan using the Wikileaks data from Mike Dewar on Vimeo.
The latest visualization of the WikiLeaks data compiled by our group is an animation of the intensity of report observations in Afghanistan over the six year period in the WikiLeaks data. Team member Mike Dewar did the vast majority of work for
Auto-completion in Notepad++ for R Script
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
Conditioning Systems on Regime Variables
Here is a brief and simple example of switching systems based upon regime type (sometimes called gating). I've brought up the idea of conditioning systems based upon regimes many times in past posts. Some texts call this filtering, although I prefer t...
How to animate Google Earth with R
We've looked before at how you can annotate geographical maps using R, but what if you want to overlay data onto a globe of the Earth, using Google Earth? The RKML package for R (from the OmegaHat project) allows you to do just that, by providing a high-level interface from R to generate KML files, which in turn are...
R and Google Earth ~ comparing tuna tracks vs. Gulf of Mexico oil spill extent
There is a lot of interest in how the Gulf of Mexico oil gusher will affect the ecosystem and its marine species. One such species is the Western Atlantic bluefin tuna that holds the Gulf of Mexico as one of its major spawning grounds. Recent tag data show that the location of the gusher is 
U.S. Unemployment Data: Animated Choropleth Maps
I was curious about creating maps with ggplot2 - and was happy to find that great minds have long since tackled this topic. Folks who are interested in how to learn about R (and ggplot2) might be interested in the process. (There should be ...
My Talk on Animations at useR! 2010 (NIST, Gaithersburg)
As every useR knows, the useR! 2010 conference is being held at NIST in Gaithersburg these days. I have just finished my talk on the R package animation this afternoon. Here are my slides and R code for those who are interested: Have fun, even if you are a PhD! Related Postsalphahull: an R Package
Hierarchical Visualizations in R and the Javascript InfoVis Toolkit
I love R. It is really a great language and platform for statistical work and graphing. But every technology has its limits - and other tools can be meet different needs. So in this post, I will start with R and move on to the JavaScr...
