Last week, Revolution Analytics released its first massive open, online course through a partnership with Introduction to Revolution R Enterprise for Big Data Analytics. You can sign up for the free course here.

The video replay from last week's Introducing Revolution R Open webinar is now available, and I've embedded it below for anyone who may have missed the live presentation.

I saw the movie Interstellar last weekend, and loved it. I'm not usually one for long movies, but it managed to sustain the excitement and wonder of Gravity for the whole 3 hours.

Plotly is a platform for data analysis, graphing, and collaboration. You can use ggplot2, Plotly's R API, and Plotly's web app to make and share interactive plots. Now, you can you can also make 3D plots. Immediately below are a few examples of 3D plots.  In this post we will show how to make 3D plots with ggplot2 and Plotly's R API.

Those performance gains mainly come from multi-threading: Revolution R Open is linked to the Intel Math Kernel Library, which uses all available cores (rather than just one core) to compute matrix and vector operations in parallel.
