The Deepwater Horizon, in context

The Earth is pretty big. Give or take, it's about 36,000 feet (11km) to the height of a 747 soaring above Everest, and (in pleasing symmetry) about the same distance down the bottom of the Mariana Trench. (Nonetheless, if you shrunk the Earth down to scale, it would still be smoother than a billiard ball.) So I was surprised...

By

Had a fun day today in a TV studio for Fox Business News, where Revolution CEO Norman Nie was giving an interview to Liz Claman at Fox Business Network. As you might expect, the interview focused a lot more on the business side than on technical capabilities of Revolution R, but there was some good discussion of the impacts...

Thoughts on Making Data Work

June 9, 2010
By

I really enjoyed all four talks at today's online conference, Making Data Work. (Disclosure: Revolution sponsored this conference.) I thought the four speakers together gave a great overview of issues related to the processing, analysis, and visualization of big data. Mike Driscoll started off with a useful categorization for data size. "Small Data" (<10Gb) fits in the memory of...

What is R?

June 7, 2010
By

Probably the question I get asked the most about R is, "What is R"? It's can be a hard question to answer, because R is so many things. It's data analysis software. It's an environment for data analysis. It's a language. It's an open-source project. It's a community. The Wikipedia page for R does a great job of describing...

Because it’s Friday: Stochastic degradation

June 4, 2010
By

When you upload a video to YouTube, they don't store a perfect digital copy of your media file. The video is actually re-encoded into the MPEG-4 video format. This saves space on YouTube's servers, but also introduces some random degradation to the video (as a result of the lossy compression process). So what happens if you then save that...

My colleague Saar Golde was having some troubles connecting Revolution R to MySQL on Windows (64-bit). Turned out the problem was the lack of an environment variable. He documented the instructions for fixing the problem on Windows 7, below. Thanks, Saar! The Problem: A client is about to send me a couple of large MySQL tables, so I needed...

Political Science with R

As a discipline, Political Science -- the analysis of the theory and practice and politics -- has been around for quite a while. (Our own CEO here at Revolution Analytics, Norman Nie, has been a leading academic and author in the field for over 40 years.) But it's only in recent years that a deluge of data about politics...

Andrew Lampitt from Jaspersoft was next up, with an overview of the Jaspersoft system for BI reports and dashboards. My section focused mainly on R and its...
