Kicking Ass with plyr

Tonight (October 29, 2009) at 5:30 PM is the Chicago R meetup at Jaks tap. Here’s more info.  I’ll be making a presentation based on my earlier blog post about plyr. The presentation will only be 8 minutes long so I’ve had to pick and choose my info carefully. OK, who am I kidding? I [...]

Why Stack Overflow Careers is a Disruptive Innovation

Today Joel (typo fixed) Jeff Atwood announced via the Stack Overflow blog a new site called Stack Overflow Careers, a programming job site focused at job hunters.  This is a compliment to the job listing service which allows companies who are hiring to advertise on Stack Overflow. Seems like the the world’s most ‘no shit’ [...]

A Fast Intro to PLYR for R

I’m not dead yet! Although it has been rumored that I am. The new job is going great and I’m thrilled to be with a new firm doing interesting work alongside smart people. It makes me seem smarter by simple association.
There’s been a lot going on recently in the R user community. There was an [...]

Tolstoy Dichotomy, Part Two

So back in March, 2009 I blogged about a phenomenon I called the Anna Karenina Yield Anomaly. In short, I postulated that in the production of crops the idea of a national ‘good year’ pretty much means everyone had a good yield and a national ‘bad year’ meant that some had an OK year and [...]

Who's Tweets Do I Read… Magic R Code Says…

So one glace at my user logs shows the truth: no one gives a rat’s rump that I just quit my job; you just love you some Twitter R code. And I’m nothing but an attention whore, so come get some!
So in my last ‘Twitter with R’ post I gave you some code I’d written [...]

Dave, over at The Revolutions Blog, posted about the big ‘ol list of graphs created with R that are over at Wikimedia Commons. As I was scrolling through the list I recognized the standard normal distribution from the Wikipedia article on the same topic.
Below is the fairly simple source code with lots of comments. Here’s [...]

Keeping Technical Talent or Why I Just Quit My Job

I’ve been a long time reader of Joel Splosky. I enjoy his writing. He is Jewish, opinionated, and successful. I, am only opinionated so I enjoy his differing experience from my own. Joel runs a software development firm in NYC. He also really understands developers. His business model is, in short: Hire great developers, keep [...]

Twitter from R… Sure, why not!

So I have started following the #RStats tag in twitter. Prior to a week ago I had never Twitterbated so I thought I would give it a go since I am not one to shy away from new technology… much. I think of Twitter like a call in radio show where I get to cut [...]

Show Me Your Hadoop

At some point I need to run some experiments on this platform. In the meantime, here’s the news. Amazon Web Services now has a Hadoop based MapReduce service called Amazon Elastic MapReduce. I thought MapReduce is what happened to me when I got a Blackberry with Google Maps and GPS integration. While having a GPS [...]

Can You Feel The Love Tonight

Today my R Resources page was the link de jour over at The Revolutions blog. So if you came here from there, welcome. And don’t touch anything here, I haven’t dusted in a while.
If you’re an R geek (stop trying to look innocent, I can see that you are) then you may find my post [...]
