I've found walk-throughs generated using knitr to be incredibly useful - they show you the commands, and the graphs/tables they generate, they often walk through in small steps so you can follow along, and you also get exposed to a bit of the thinking behind - how to approach analysing different data sets. My friend just posted this analysis of school board data: http://rpubs.com/dirkchen/knaer-tdsb http://rpubs.com/dirkchen/knaer-tdsb. RPubs is awesome, you can also browse the front page http://rpubs.com http://rpubs.com, since all documents are public. Lot's to learn here. Two things that would make this easier: One is some more social features on the site, like tagging and voting up (show me examples with scatterplots, etc). It would also be great if there was an option to upload the Rmd sheet, as well as the data files when publishing. Of course, some people publish their entire projects to GitHub, but if it was a lot more convenient, perhaps more people would share - one-button import into your own RStudio, for your own experimentation, would be awesome.
