I was very happy to have been able to attend R / Finance 2014 which wrapped up a couple of weeks ago. In general, the talks were at a very high level of play, some dealing with brand new ideas and many presented at a significant level of technical or mathematical sophistication. Fortunately, most of the slides from the presentations are quite detailed and available at the conference site. Collectively, these presentations provide a view of the boundaries of the conceptual space imagined by the leaders in quantitative finance. Some of this space covers infrastructure issues involving ideas for pushing the limits of R (Some Performance Improvements for the R Engine) or building a new infrasturcture (New Ideas for Large Network Analysis) or (Building Simple Data Caches) for example. Others are involved with new computational tools (Solving Cone Constrained Convex Programs) or attempt to push the limits on getting some actionable insight from the mathematical abstrations: (Portfolio Inference withthei One Wierd Trick) or (Twinkle twinkle litle STAR: Smooth Transition AR Models in R) for example.
But while the talks may be illuminating, the real takeaways from the conference are the R packages. These tools embody the work of the thought leaders in the field of computational finance and are the means for anyone sufficiently motivated to understand this cutting edge work. By my count, 20 of the 44 tutorials and talks given at the conference were based on a particular R package. Some of the packages listed in the following table are wellestablished and others are workinprogress sitting out on RForge or GitHub, providing opportunities for the interested to get involved.

Many thanks to the organizers of the conference who, once again, did a superb job, and to the many professionals attending who graciously attempted to explain their ideas to a dilletante. My impression was that most of the attendies thoroughly enjoyed themselves and that the general sentiment was expressed by the last slide of Stephen Rush's presentation:
Rbloggers.com offers daily email updates about R news and tutorials on topics such as: visualization (ggplot2, Boxplots, maps, animation), programming (RStudio, Sweave, LaTeX, SQL, Eclipse, git, hadoop, Web Scraping) statistics (regression, PCA, time series, trading) and more...
