Earlier this month the Bay Area useR Group (BARUG) held it annual lightning talk meeting. This is by far our most popular meeting format: eight, 15 minute talks (12 minutes speaking and 3 minutes Q & A while the next speaker is setting up) packed into a two hour time slot. The intensity seems to really energize the speakers and engaged the audience. 

R user and developer Lionel Henry proposes a number of changes to R syntax:

Use square brackets to create lists. You could use [1, 2:5, "hello"] to create a list of three elements. Nested lists would be possible as well, with syntax like or [ [1, 2], [2, 3] ] (much easier than list(list(1,2),list(2,3))).

Interesting to see this union of modern dance and computer imagery:

It's not clear whether this is just pre-recorded graphics combined with well-timed choreography, or if the images are actually reacting to the dancer's movements. I suspect the former in this case (filmed in 2014), but recent advances in real-time motion detection should make true reactivity between dancers and the virtual environment possible. I hope to see something like that on stage someday soon.

The latest update to RStudio, the cross-platform open-source integrated development environment for the R language from the team at RStudio, adds many new features for R developers. But perhaps the most significant update is one which allows R developers to add their own new features to RStudio: add-ins. 

In case you missed them, here are some articles from January of particular interest to R users.

The first meeting of R users in Poland took place in Wroclaw in 2008. It was a one-day conference with 27 participants and 6 talks.

If you have a database of credit-card transactions with a small percentage tagged as fraudulent, how can you create a process that automatically flags likely fraudulent transactions in the future? That's the premise behind the latest Data Science Deep Dive on MSDN.
