Presented by Hadley Wickham, Assistant Professor, Dobelman Family Junior Chair, Department of Statistics, Rice University.
ABSTRACT
Data analysis, the process of converting data into knowledge, insight and understanding, is a critical part of statistics, but there's surprisingly little research on it. In this talk I'll introduce some of my recent work, including a model of data analysis. I'm a passionate advocate of programming that data analysis should be carried out using a programming language, and I'll justify this by discussing some of the requirement of good data analysis (reproducibility, automation and communication). With these in mind, I'll introduce you to a powerful set of tools for better understanding data: the statistical programming language R, and the ggplot2 domain specific language (DSL) for visualisation.

I wish that I had formal instruction in use of R. As someone who tried to get into it completely independently and apply it to my research, I felt totally lost and that it would be clearly a loosing proposition. Even the first time I tried to install it an error was thrown and I can't use it at all. Searched and found other people had the same problem... and it pretty much ended there.
