Microsoft officially launched SQL Server 2016 at the Data Driven event in New York City last week, and R featured prominently.

So you've boarded the plane and settled into your seat, ready for your trip to a holiday paradise for a well-earned vacation. But then there's that dreaded announcement from the cockpit, where the pilot announces that she's "got a light on the dashboard", and needs to send in a maintenance crew to check it out. Before you know it, you've been sitting on the tarmac for an hour, you're probably going to miss your connection, and the trip is already off to a bad start.

Here's an interesting way of looking at music: the Pianogram, by Joey Cloud. The white and black keys are extended by their frequency in the music piece. It's not a very representative histogram, mind you: the key lengths aren't really representative of frequency because they extend into the "base" piano figure but still: neat. You can upload a MIDI file of any music you choose.

Evaluation metrics are the key to understanding how your classification model performs when applied to a test dataset. In what follows, we present a tutorial on how to compute common metrics that are often used in evaluation, in addition to metrics generated from random classifiers, which help in justifying the value added by your predictive model, especially in cases where the common metrics suggest otherwise.

The R Core Group announced yesterday the release of R 3.2.4, the final update in the R 3.2.x series. (R 3.3.0 is scheduled for release on April 14.) This update, codenamed "Very Secure Dishes", makes a few minor improvements and bug fixes, including long vector support for the smooth function, some improvements in package installation, and a few accuracy improvements for edge-cases in some statistical functions.

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