I had no intention to blog this, but @jayjacobs convinced me otherwise. I was curious about the recent (end of March, 2014) California earthquake “storm” and did a quick plot for “fun” and personal use using ggmap/ggplot. I used data from the Southern California Earthquake Center (that I cleaned up ... [Read more...]

Andy Kirk (@visualisingdata) & Lynn Cherny (@arnicas) tweeted about the Guardian Word Count service/archive site, lamenting the lack of visualizations: Want to know num of words written in each day's Guardian paper by section + approx reading time? http://t.co/wP4W1EzUsx via @bengoldacre— Andy Kirk (@visualisingdata) March 15, 2014 This ...

I shot a quick post over at the Data Driven Security blog explaining how to separate Twitter data gathering from R code via the Ruby t (github repo) command. Using t frees R code from having to be a Twitter processor and lets the analyst focus on analysis and visualization, ... [Read more...]

I’m posting this mostly to show how to: use the Google spreadsheet data-munging “hack” from the previous post in a Shiny context include it seamlessly into a web page, and run it locally without a great deal of wrangling The code for the app is in this gist. It ... [Read more...]

The “medals” R post by TRInker and re-blogged by Revolutions were both spiffy and a live example why there’s no point in not publishing raw data. You don’t need to have R (or any other language) do the scraping, though. The “IMPORTHTML” function (yes, function names seem to ... [Read more...]

Jay Jacobs (@jayjacobs)—my co-author of the soon-to-be-released book Data-Driven Security—& I have been hard at work over at the book’s sister-blog cranking out code to help security domain experts delve into the dark art of data science. We’ve covered quite a bit of ground since January 1st, ... [Read more...]

RStudio is my R development environment of choice and I work primarily on/in Mac OS X. While it’s great that Apple provides a built-in Terminal application, I prefer to use iTerm 2 when I need to do work at a shell. The fine folks at RStudio provide a handy ... [Read more...]

I decided to forego the D3 map mentioned in the previous post in favor of a Shiny one since I had 90% of the mapping code written. I binned the ranges into three groups, changed the color over to something more pleasant (with RColorBrewer), added an interactive table for the counties ... [Read more...]

Avast me hearRties! (ok, enough of the pirate speak in a blog post) It wouldn’t be TLAPD without out some modest code & idea pilfering from Mark Bulling & Simon Raper. While those mateys did a fine job hoisting up some R code (your really didn’t think I’d stop ... [Read more...]

R lacks some of the more “utilitarian” features found in other scripting languages that were/are more geared—at least initially—towards systems administration. One of the most frustrating missing pieces for security data scientists is the lack of ability to perform basic IP address manipulations, including reverse DNS resolution (... [Read more...]
