From the website:
Projects in rOpenSci fall into two categories: those for working with the scientific literature, and those for working directly with the databases. Visit the active development hub of each project on github, where you can see and download source-code, see updates, and follow or join the developer discussions of issues. Most of the packages work through an API provided by the resource (database, paper archive) to access data and bring it within reach of R’s powerful manipulation.
Project started this past summer but has already collected some tutorials and data.
Good opportunity to learn some R as well as talk up the notion of re-using scientific data in new ways. Don’t jump right into recursion of subject identity as it relates to data, data structures and the subject both represent. YOU MAY THINK THAT, but what you say is: How do you say when you are talking about the same subject across data sets? Would that be useful to you? (Note the strategy of asking the user, not explaining their problem first. The explaining of their problem for them in terms I understand is mostly my strategy so this is a reminder to me to not do that!)
