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.

Quite the morbid fascination. I was impressed with the Death Map of Mexico though (and in so few lines of code)!

Data analysis is the process by which data becomes understanding? I do not agree. Does understanding start with data analysis? Is there no understanding to raise a hypothesis and to make the experimental design before even collecting data? It is just the end of the process of understanding.

This guy really needs to study geography. Mexico City is over 2500 m over sea level, how can you study temperatures in a city and not research the most basic facts about its geographic attributes?
