Two months ago there was a discussion in the ESS mailing list about Emacs/ESS started by Paul Johnson, who claimed "Emacs Has No Learning Curve". While this sounds impossible, he really has some good points, e.g. he encourages beginners to look at the ...
After last week's kerfuffle I hope the roll out of googleVis version 0.3.2 will be smooth. To test the water I release this version into the wild here and if it doesn't get shot down in the next days, then I shall try to upload it to CRAN. I am mindful...
I have been traveling during the last two weeks. I visited Fred Hutchinson Cancer Research Center on Oct 16 and the Department of Biostatistics at Johns Hopkins at the invitation of Simply Statistics on Oct 23. Today Christian Robert was visiting our department at Iowa State, and I also talked to him. It is really cool...
Many R users may still remember the good old days when we had static HTML documentation for R packages. That was probably before R 2.10.0 (in 2009). Then we had the fancy dynamic HTML help based on the built-in httpd server, but it has never really mad...

This is a quick follow-up to my previous post about Color Palettes in RGB Space. Achim Zeileis had commented that, perhaps, it would be more informative to evaluate the color palettes in HCL (polar LUV) space, as that spectrum more accurately describes how humans perceive color. Perhaps more clear trends would emerge in HCL space,
The third Cologne R user meeting took place last Friday, 5 October 2012, at the Institute of Sociology. The evening was sponsored by Revolution Analytics, who provided funding which went towards the Kölner R user group Meetup page. We had a good tur...
I need to simulate balanced and unbalanced phylogenetic trees for some research I am doing. In order to do this, I do rejection sampling: simulate a tree -> measure tree shape -> reject if not balanced or unbalanced enough. But what is enough? We ne...
