Last years UseR 2012 conference in Nashville had an interesting discussion session titled “What other languages should R users know about?“. General consensus was that multilingualism is inevitable in modern computing, and panel members presented various languages that complement R in different ways. Some of the usual suspects included SQL, python, and of course C++, ...

Tutorial- Building Biological Networks
I love networks! Nothing is better for visualizing complex multivariate relationships be it social, virtual or biological. I recently gave a hands-on network building tutorial using R and Cytoscape to build large biological networks. In these networks Nodes represent metabolites and edges can be many things, but I specifically focused on biochemical relationships and chemical 
An Introduction to SAS for R Programmers
by Joseph Rickert Life decisions are usually much too complicated to be attributed to any single cause, but one important reason that I am here at Revolution today is that I ignored suggestions from well-meaning faculty back in graduate school to work more in SAS rather than doing everything in R. There was a heavy emphasis on SAS then:...
List of Bioinformatics Workshops and Training Resources
I frequently get asked to recommend workshops or online learning resources for bioinformatics, genomics, statistics, and programming. I compiled a list of both online learning resources and in-person workshops (preferentially highlighting those where workshop materials are freely available online):

“Building ractives is so addictive it should be illegal!”
clickme is an amazing R package. I was not sure what to expect when I first saw Nacho Caballero's announcement. I actually was both skeptical and intimidated, but neither reaction was justified. The examples prove its power, and his wiki tutorials ease...
Automatic ARMA/GARCH selection in parallel
In the original ARMA/GARCH post I outlined the implementation of the garchSearch function. There have been a few requests for the code so … here it is. Quite easy to use too: After the last code line above, fit contains the best (according to the AIC statistic) model, which is the return value of garchFit.
