Fun with .Rprofile and customizing R startup

Fun with .Rprofile and customizing R startup

Over the years, I've meticulously compiled–and version controlled–massive and extensive configuration files for virtually all of my most used utilities, most notably vim, tmux, and zsh. In fact, one of the only configurable utilities for which I had no special configuration schema was R. This is extremely surprising, given that I use R everyday. One »more

I was offline much of the day Tuesday and completely missed Hadley Wickham’s tweet about the new rvest package: Are you an #rstats user who misses python's beautiful soup? Please try out rvest (http://t.co/PeiIHr3jDW) and let me know what you think.— Hadley Wickham (@hadleywickham) September 12, 2014 My intrepid colleague (@jayjacobs) informed me of this (and didn’t...

Bayes says “don’t worry” about Scotland’s Referendum

Just few hours before Scots head to the polls, there is not an overwhelming advantage of the anti-independence vote. Actually, the margin is shorter than last time I looked at it, but despite such a growing trend in favor of the "Yes" campaign in the last weeks, the "NO" side has an edge still. To … Read More...

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...

How accurate is Next Bus III: getting the answers

So now that we’ve collected data from the web and wrangled it into something useful, what can we say about how accurate Next Bus is? This post is about the “making of the analysis” … which might be rather boring to those non data geeks (normal people). If you’re just interested in the story and the pictures,...

This post displays two animated choropleths. One for global mortality rates for children under 5 (per 1000 live births) and the second for the difference in global mortality rates for males and female children under 5 (per 1000). This was put together after my wife sent a link to this optimistic story on NPR’s site. It was regarding...

Using great circles and ggplot2 to map arrival/departure of 2014 US Open Tennis Players

Thanks to Alex Bresler and Aragorn Technologies for the data and opportunity to work with a great group of people. In this one, we’ll take a look at player’s countries, particularly the potential flight paths to and from New York...

R package to convert statistical analysis objects to tidy data frames

September 16, 2014
By

I talked a little bit about tidy data my recent post about dplyr, but you should really go check out Hadley’s paper on the subject. R expects inputs to data analysis procedures to be in a tidy format, but the model output objects that you get back aren’t always tidy. The reshape2, tidyr, and dplyr are meant to...
