(This article was first published on

**Quantum Forest » rblogs**, and kindly contributed to R-bloggers)Man flu kept me at home today, so I decided to do something ‘useful’ and go for a linkathon:

- Ed Yong discusses the effect of subject expectations in psychology experiments Nice Results, But What Did You Expect? At the beginning there was another article on The placebo phenomenon, and another one on The placebo defect.
- A googleVis tutorial to create Hans Rosling-type graphs from R.
- Google’s Python Class is material for an intensive 2-day course on Python.
- An opinion piece on Calculus and statistics by Daniel Kaplan, on teaching a different version of your typical introductory calculus course, so it is useful for statistics. He goes as far as teaching calculus using R. There is more information in Project MOSAIC.
- Nice graphs on what happened to Asiana Airlines flight 214. I didn’t know there was so much available data for a specific flight.
- Biased and Inefficient, Thomas Lumley’s personal statistics blog (he insists that posting 75% of Statschat is not enough to qualify as personal). You may know Thomas from the survey package (or a few others).
- My previous post the USA versus Western Europe comparison of GM corn was the first time that I received more traffic from Facebook than from R-bloggers. Five hundred readers in total.

Sometimes people are truthful and cruel. Here Gappy on a mission goes for the jugular:
