On his recent tour to the Bay Area, Hadley Wickham have two interesting R-related talks, for which video has been made available by Google Tech Talks.

At the June Bay Area R User Group meeting, Hadley spoke on the future of interactive data visualization in R. Building on his experiences creating the ggplot2 package (which is still under development -- he's working to improve its performance and to visualize massive data sets with the Revolution Analytics big-data objects, for example), he's also working on a series of packages to make it possible to write high-performance interactive graphics just using R code. In the video below, he gives examples of pointing-and-clicking to reveal data on maps, to interact with code profiles to optimize performance, and creating a series of linked charts (where, say, a data value highlighted on a scatterplot will also highlight the same value in a parallel coordinates plot). The plan is to have these new pacakges available by the end of the Summer.

 

His second talk (a Google Tech Talk) was about why engineers should use a programming language (specifically, R) for analyzing data. It's a more general introduction to data analysis and the benefits of programming with data, and would be a great introductory video for anyone new to R. 

 

Hadley is also giving a two-day short course on Data Visualization and the Analysis of Financial Time Series in Houston in July (follow the link for details and registration info).
