Overcoming D3 Cartographic Envy With R + ggplot

Overcoming D3 Cartographic Envy With R + ggplot

When I used one of the Scotland TopoJSON files for a recent post, it really hit me just how much D3 cartography envy I had/have as an R user. Don’t get me wrong, I can conjure up D3 maps pretty well and the utility of an interactive map visualization goes without saying, but

Google location data — Where I’ve been.

I was emailed by a friend that was looking into their google location data and had asked if I had ever used a json file before in R. I said I had not, but I knew there were packages to do such things. The things I sent were things he had already tried,...

Seeing the (day)light with R

The arrival of the autumnal equinox foreshadows the reality of longer nights and shorter days here in the northeast US. We can both see that reality and distract ourselves from it at the same time by firing up RStudio (or your favorite editor) and taking a look at the sunrise & sunset times based on

Newcastle R course, a write-up

September 22, 2014
By

I recently attended a week-long R course in Newcastle, taught by Colin Gillespie. It went from “An Introduction to R” to “Advanced Graphics” via a day each on modelling, efficiency and programming. Suffice to say it was an intense 5 days! Overall it was the best R course I’ve been on so far. I’d recommend it to others,...

Ebola, Wikipedia and data janitors

Sometimes, several strands of thought come together in one place. For me right now, it’s the Wikipedia page “Ebola virus epidemic in West Africa”, which got me thinking about the perennial topic of “data wrangling”, how best to provide public data and why I can’t shake my irritation with the term “data science”. Not to

Charting/Mapping the Scottish Vote with R (an rvest/dplyr/tidyr/TopoJSON/ggplot tutorial)

The BBC did a pretty good job live tracking the Scotland secession vote, but I really didn’t like the color scheme they chose and decided to use the final tally site as the basis for another tutorial using the tools from the Hadleyverse and taking advantage of the fact that newer gdal libraries can read

Space Invaders

I burned through all of my extra lives in a matter of minutes, and my two least-favorite words appeared on the screen: GAME OVER (Ernest Cline, Ready Player One) Inspired by the book I read this summer and by this previous post, I decided to draw these aliens: Do not miss to check this indispensable document to choose

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

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,...
