[R] Input appreciated: R teaching idea + a way to improve R-wiki

[Ari Friedman]

Just want to chime in and say that I think it's a great idea.  It is, 
after all, a wiki, and even the bad entries will serve to be something 
like stubs that can be expanded upon by others and they play with them.  
When using e.g. the Gentoo wiki, I have run across some well-organized 
entries (as, it seems, all of these would be) that are nevertheless 
incorrect and/or missing steps.  They have nonetheless been quite 
valuable, as they got me pointed in the right direction, and I could 
later come back and patch them up with what I'd learned.
