List of R programmers: Hello R people. In December of 2013 I posted a cheap-o wiki-editable (thank you github) contact list which recruiters can use to find you, if they’re looking for R programmers. In what I consider a resounding success, within a few weeks it got onto the first page of google (thank you github), and...

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

I love dplyr. It's my "go-to" package in R for data exploration, data manipulation, and feature engineering. I use dplyr because it saves me time: its performance is blazing fast on data frames, but even more importantly, I can write dplyr code faster ...

September 22, 2014

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”.

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
