The code-books are often as indispensable as they are massive, and not always as clear as one would want. Routings, and resulting and strange patterns of missing values are at times difficult to find. I found a nice way to plot missing values, using R. Basically, I thought it would be nice to calculate the percentage of missings on each variable, and do so for each year represented in the data. These numbers could be visualized using a levelplot(), which resulted in the graph below.]]> http://www.rensenieuwenhuis.nl/r-sessions-30-visualizing-missing-values/feed/ 1 R-Sessions 29: Running R-Project twice on Apple Mac OS X http://www.rensenieuwenhuis.nl/r-sessions-29-running-r-project-twice-on-apple-mac-os-x/ http://www.rensenieuwenhuis.nl/r-sessions-29-running-r-project-twice-on-apple-mac-os-x/#comments Mon, 24 Nov 2008 10:00:40 +0000 Rense Nieuwenhuis http://www.rensenieuwenhuis.nl/?p=835 http://www.rensenieuwenhuis.nl/r-sessions-29-running-r-project-twice-on-apple-mac-os-x/feed/ 3 A Very Small Step for Read.isi … http://www.rensenieuwenhuis.nl/a-very-small-step-for-readisi/ http://www.rensenieuwenhuis.nl/a-very-small-step-for-readisi/#comments Wed, 05 Nov 2008 10:00:02 +0000 Rense Nieuwenhuis http://www.rensenieuwenhuis.nl/?p=783 http://www.rensenieuwenhuis.nl/a-very-small-step-for-readisi/feed/ 2 R-Sessions 28: Impressive R Speeds http://www.rensenieuwenhuis.nl/r-sessions-28-impressive-r-speeds/ http://www.rensenieuwenhuis.nl/r-sessions-28-impressive-r-speeds/#comments Thu, 30 Oct 2008 10:00:22 +0000 Rense Nieuwenhuis http://www.rensenieuwenhuis.nl/?p=778 http://www.rensenieuwenhuis.nl/r-sessions-28-impressive-r-speeds/feed/ 4 The R-Sessions Forum: Introducing a new forum on R-Project http://www.rensenieuwenhuis.nl/the-r-sessions-forum/ http://www.rensenieuwenhuis.nl/the-r-sessions-forum/#comments Mon, 20 Oct 2008 10:00:55 +0000 Rense Nieuwenhuis http://www.rensenieuwenhuis.nl/?p=726 R-Sessions Forum: a new forum on R-Project and statistics in general. This new forum is closely integrated with , but has its own dynamic. The R-Sessions Forum aims at providing a flexible stage for visitors interested in discussing both R-Project and general statistics.

Topics & Features

The new R-Sessions Forum has several interesting features and covers many topics. Amongst the new topics covered are integration with the R-Sessions on Curving Normality, a section for general question on R, a section for general statistical questions, package specific questions, R development, and of course we have a pub for your general chatter. The integration with the R-Sessions is intended to give more dynamic ways of interacting with the Curving Normality web-site. The other topics are more general in nature and provide ample opportunity to pose your own questions and discuss those with other participants. ]]> http://www.rensenieuwenhuis.nl/the-r-sessions-forum/feed/ 3 R-Sessions 27: Text Editors for R: Textmate http://www.rensenieuwenhuis.nl/r-sessions-27/ http://www.rensenieuwenhuis.nl/r-sessions-27/#comments Thu, 16 Oct 2008 10:14:33 +0000 Rense Nieuwenhuis http://www.rensenieuwenhuis.nl/?p=686 TextMate, a paid application marketed as 'The Missing Editor for Mac OS X'. Designed explicitly for use by programmers on Mac OS X, TextMate makes a promising first impression. The interface looks very clean, text is rendered perfectly, and syntax colouring is provided for quite a large number of programming languages. Also, the colouring of the syntax looks very nice, by the use of light colours that don't interfere with reading the text.]]> http://www.rensenieuwenhuis.nl/r-sessions-27/feed/ 2
