Why Do the New Orleans Saints Lose?…

Why Do the New Orleans Saints Lose? Data Visualization II by Nathan Lemoine.

I’m not a nationalist, apparatchik, school, state, profession, class, religion, language or development approach booster.

I must confess, however, I am a New Orleans Saints fan. Diversity, read other teams, are a necessary evil to give the Saints someone to beat. ;-)

An exercise you can repeat/expand with other teams (shudder), in other sports (shudder, shudder), to explore R and visualization of data.

What other stats/information would you want to incorporate/visualize?

ggplot2

From the webpage:

ggplot2 is a plotting system for R, based on the grammar of graphics, which tries to take the good parts of base and lattice graphics and none of the bad parts. It takes care of many of the fiddly details that make plotting a hassle (like drawing legends) as well as providing a powerful model of graphics that makes it easy to produce complex multi-layered graphics.

I have a few posts about ggplot2 but this site is the mother ship of information on it. Use other resources as necessary but this looks like the canonical source. (Plus you can download a local copy for your laptop. For the odd occasion when you are off net.)

ggplot posixct cheat sheet

From the brain of Mat Kelcey, a cheatsheet of common plots using ggplot.

Any common plots in your toolbox?

Slides and replay for “A backstage tour of ggplot2″

From the post:

Many thanks to Hadley Wickham for his informative and entertaining webinar yesterday, “A backstage tour of ggplot2″. Thanks also to everyone who submitted questions — with more than 800 attendees live on the line we had many more questions than we had time to answer.

Pointers to lots of goodies and video of the presentation!

Great Maps with ggplot2

Great Maps with ggplot2

I have mentioned ggplot2 before but this item caught my eye because of its skillful use with a map of cycle tours of London.

Not that I intend to take a cycle tour of London any time soon but it occurs to me that creating maps to resturants, entertainment, etc., from conference sites would be a good use of it. Coupled with a topic map, as the conference progresses, reviews/tweets about those locations could become available to other participants.

Other geographic locations/information could be plotted as well.

A Backstage Tour of ggplot2 with Hadley Wickham

Thursday, January 12th, 2012

A Backstage Tour of ggplot2 with Hadley Wickham

Details:

Date: Wednesday, February 8, 2012
Time: 11:00AM – 12:00PM Pacific Time
Presenter: Hadley Wickham, Professor of Statistics, Rice University

From the webpage:

GGplot2 is one of R’s most popular, widely used packages, developed by Rice University’s Hadley Wickham. Ggplot2’s exploratory graphics capabilities are driving the use of R as a complement to legacy analytics tools such as SAS. SAS is well-regarded for its strength in data management and “production” statistics, where you know what you want to do and need to do it repeatedly. On the other hand, R is strong in data analysis and exploration in situations where figuring out what is needed is the biggest challenge. In this important way, SAS and R are strong companions.

This webinar will provide an all-access pass to Hadley’s latest work. He’ll discuss:

  • A brief overview of ggplot2, and how it’s different to other plotting systems
  • A sneak peek at some of the new features coming to the next version of ggplot2
  • What’s been learned about good development practices in the 5 years since first starting to develop ggplot
  • Some of the internals of ggplot2, and talk about how he is gradually making it easier for others to contribute

Join this webinar to understand how ggplot2 adds valuable, unmatched capabilities to your analytics toolbox.
