As usual, the Guerrilla Data Analysis Techniques (GDAT) class was a total blast. Motivated students always guarantee that. It would really help our scheduling, however, if people didn't wait until the last nanosecond to register for the class. But give...
I haven't posted much here recently, but here is a roundup of a few of the links I've shared on Twitter (@genetics_blog) over the last two weeks.Here is a nice tutorial on accessing high-throughput public data (from NCBI) using R and Bioconductor.Cloud...
R isn't just about serious things like model inference and prediction intervals and big analytics. Sometimes, R lets its hair down and just does weird and wonderful things because ... well just because. For example, with a package from Paulo Sonego, it can display your favourite XKCD cartoon: > install.packages("RXKCD", repos="http://R-Forge.R-project.org",type="source") > searchXKCD("support") num title 1 8 Red spiders...
The title of chapter 5 in my Guerrilla Capacity Planning book is, "Evaluating Scalability Parameters," and underneath it you'll see this quote:
"With four parameters I can fit an elephant. With five I can make his trunk wiggle." —John von NeumannIn that vein, Guerrilla alumnus Stephen O'C. pointed me at a recent blog post and paper (PDF)...
R bloggers (including me) typically post plots online as portable network graphics (PNG). This is silly because plots generally work better as vector graphics. For years I’ve wanted to host scalable vector graphics (SVG) online, but none of the ima...
Yesterday Brett Goldstein, the Chief Data Officer for the City of Chicago, announced on Twitter the release of Chicago’s crime data for the past year. The data is very detailed, and wonderful resource for criminologist and social scientists alike.
I have been playing around with the data a bit, and have produced an animation
Using ImageMagick it's pretty easy to make an animated gif from a set of plots. Essentially the way to do it is to save a plot for each frame of the animation and then convert them into a .gif. Here's a simple example that plots binomial density's for ...
In undergrad I had a computer science professor that piqued my interest in applied mathematics, beginning with Conway’s Game of Life. At first, the Game of Life (not the board game) appears to be quite simple — perhaps, too simple — but it has been widely explored and is useful for modeling systems over time.

A couple weeks ago, I received an email from a fellow Pitch F/Xer and R-User, Josh Weinstock, asking if I was interested in a guest post here at Prince of Slides. I didn't think I was important enough to have talented guests posting at my blog; howeve...
