I just added a new video to the R repository, and this one comes from the Los Angeles R Meetup. The folks in LA were fortunate enough to have Dirk Eddelbuettel—renowned R expert and StackOverflow super-user—discuss his joint work with Romain François for interfacing C++ and R code using the Rcpp package. For those

How to Produce Fake Data Analysis in R: 3 Easy Steps
Did you really think that a team of researchers spent their weekends counting the number of shirtless adolescent men and exposed penises they could find on charoulette.com? Perhaps you should not answer that, as it may be a better measure of your opinion of sociologist than gullibility. It is true, sociologist do say the
How Misinformed are Tea Party Protesters About Tax Policy?
For those of you used to reading about international relations, I apologize for the following brief foray into American politics. It appears that the American Enterprise Institute and David Frum have decided to (abruptly) part ways. Before David left, however, he and his team of interns provided some interesting statistical insight into the
Happy Anniversary NYC R Meetup
Today is the one year anniversary of the NYC R Statistical Meetup. Starting as a small group meeting in a crowded conference room, Josh Reich established the meetup as the premiere gathering of data geeks in the tri-state area. Over the past year we have had 10 meetups, and two more upcoming on the

Predicting the Locations of ‘Emergency’ Ushahidi Reports in Port-au-Prince, and Implications for Crowdsourcing
Recently, Patrick Meier, PhD candidate at Tufts University and member of the Ushahidi Advisory Board, provided me with a dataset containing the first 72 hours of reports registered with Ushahidi in Port-au-Prince after the January 12th earthquake.

What Countries are ‘Pulling their Weight’ for Haiti?
Using the data provided ReliefWeb on the Appeals and Funding to Haiti (h/t DataBlog) and the most recent GNP estimates, I decided to do a little “back of the envelope” analysis. With GNP as a proxy for a country’s wealth, the hypothesis is that pledges should roughly be a linear function of wealth, i.e., the
Donate to the R Video Hosting Fund
Today I finished uploading a couple new talks to the growing repository of online presentations from the NYC R Statistical Meetup. Going forward, my plan is—whenever possible—to make all talks and presentation materials available online, in an effort to reach as wide an audience as possible. Our volunteer speakers bring immense expertise to these
Learning R via Python…or the other way around (with video!)
Last night I was one of five speakers at the NYC R Statistical Programming Meetup. The topic last night was dubbed the R Rosetta Stone, and the intent was to show how R as a language translated into several other analytical platforms and programming languages. Other speakers covered MATLAB, SAS, SQL/Postges and Clojure/Incanter—I
