In case you missed it: September 2014 Roundup

October 8, 2014

In case you missed them, here are some articles from September of particular interest to R users. Norm Matloff argues that T-tests shouldn't be part of the Statistics curriculum and questions the "star system" for p-values in R. A nice video introduction to the dplyr package and the %>% operator, presented by Kevin Markham. An animation of police militarization...

Plot Me Like a Hurricane (a.k.a. animating historical North Atlantic basin tropical storm tracks)

October 7, 2014
By

Markus Gessman (@MarkusGesmann) did a beautiful job Visualising the seasonality of Atlantic windstorms using small multiples, which was inspired by both a post by Arthur Charpentier (@freakonometrics) on using Markov spatial processes to “generate” hurricanes—which was tweaked a bit by Robert Grant (@robertstats)—and Gaston Sanchez‘s Visualizing Hurricane Trajectories RPub. I have some history with hurricane

Police militarization in the US, over time

The militarization of local police departments here in the US has been much in the news lately, and the New York Times published in June an in-depth article on how materiel from wars has ended up in the hands of US counties. Besides the traditional reporting it's a fantastic piece of data journalism: the Times submitted a freedom-of-information request...

Around the world in 80k miles

You're probably familiar with the classic Travelling Salesman problem: given (say) 20 cities, what is shortest route you can take that passes through all 20 cities and returns to the starting point? It's a difficult problem to solve, because you need to try all possible routes to find the minimum, and there are a LOT of possibilities. For a...

The Traveling Salesman with Simulated Annealing, R, and Shiny

I built an interactive Shiny application that uses simulated annealing to solve the famous traveling salesman problem. You can play around with it to create and solve your own tours at the bottom of this post. Here's an animation of the annealing process finding the shortest path through the 48 state capitals of the contiguous...

The book, I conclude, “is the authoritative resource on R’s spatial capabilities” and should be of interest to many R users. Below is a preprint of the full review, now published on ASAP’s website. As a geographer and heavy R user,...

Because it’s Friday: A 3-minute movie in 4095 bytes

August 22, 2014
By

This entire movie — images, music, everything — is generated from a Windows PC executable of just 4,095 bytes. That's not a typo: we're not talking bytes not megabytes or gigabytes here. Less than 4kb total creates this entire scene. For comparison, a medium-quality video file of this exact same scene in AVI format comes in at over 64Mb:...
