It turns out there's another local R user group in Cambridge, UK. It's called CambR, and organizing committee member Laurent Gatto described its history to me in an email: After meeting repeatedly at several R related conferences (Bioconductor meetings, useR 2011), some R enthusiasts thought Cambridge deserved a local R user group and founded CambR in September 2011.

Monitoring Progress Inside a Foreach Loop
The foreach package for R is excellent, and allows for code to easily be run in parallel. One problem with foreach is that it creates new RScript instances for each iteration of the loop, which prevents status messages from being logged to the console output. This is particularly frustrating during long-running tasks, when we are often unsure...

Parallel R Model Prediction Building and Analytics
Modifying R code to run in parallel can lead to huge performance gains. Although a significant amount of code can easily be run in parallel, there are some learning techniques, such as the Support Vector Machine, that cannot be easily parallelized. However, there is an often overlooked way to speed up these and other models. It...

SOPA and PIPA damage the Internet – R-bloggers off-topic post
Dear R people, It is a (VERY) rare event that I allow a non-R related content on R-bloggers. Today is one such rare a day. I do this in order to raise awareness of two bills in congress: H.R.3261 “Stop Online Piracy Act” and S.968 “PROTECT IP”, which could radically change the landscape of the Internet. These bills provide overly broad mechanisms...
