Using R and Ruby - slides from February LRUG

February 15, 2009

Introduction

Last week I gave a short talk at the February LRUG meeting about using the scientific programming environment R together with Ruby.

My presentation gave a few examples of the kind of statistical analysis that can be performed with R, and showed how easy this functionality is to access from within your Ruby code.

I'll post the code for the Twitter analysis to github soon. It needs a little tidying up first.

An initial draft of this presentation used R to develop a recommendation algorithm (using a k-means clustering) using the GitHub api. Although it worked, the recommendations it made were not great, so I removed the code from the presentation and replaced it with the Twitter analysis. I'd like to resurrect this code at some point, so remember to subscribe to my RSS feed if you're interested, or nag me to do it in the comments field below!
