Many R scripts depend on CRAN packages, and most CRAN packages in turn depend on other CRAN packages. If you install an R package, you'll also be installing its dependencies to make it work, and possibly other packages as well to enable its full functionality.

It's been a super-busy time at Strata this week, so I'm taking the easy route for Because it's Friday this week: funny dog and cat videos. If you're not one of the 10 million people who have seen Sad Dog Diary, well, now's your chance:

That's all for this week! Have a great weekend, and we'll be back on Monday.

There is something about R user group meetings that both encourages, and nourshies a certain kind of "after hours" creativity. Maybe it is the pressure of having to make a presentation about stuff you do at work interesting to a general audience, or maybe it is just the desire to reach a high level of play.

Here are a couple of examples of what I mean.

For the past 7 years, Revolution Analytics has been the leading provider of R-based software and services to companies around the globe. Today, we're excited to announce a new, enhanced R distribution for everyone: Revolution R Open.

Recap of Part 1

In our previous article, we introduced the four-parameter Generalized Lambda Distribution (GLD) and looked at fitting a 20-year set of returns from the Wilshire 5000 Index, comparing the results of two methods, namely the Method of Moments, and the Method of Maximum Likelihood.  

The ability to create reproducible research is an important topic for many users of R. So important, that several groups in the R community have tackled this problem.

A friend was extolling the benefits of real paper books the other day, so I sent him this. Apparently, IKEA thinks the same way.


That's all for this week — we've been very busy getting ready for the Strata conference in New York. Have a great weekend, and maybe see you there!
