The open source statistical software R has a range of contributed packages. Some of them include datasets.

I teach research methods in psychology and I'm looking for interesting real-world dataset to use as the basis for tutorials. I've found a few in contributed R packages (e.g., AER, psych), but I'm not aware of a general resource listing packages that supply multiple interesting, real-world, psychological datasets. In particular, some textbooks have an aligned R package containing many interesting datasets.

• What R packages include multiple interesting, real-world, psychological datasets?
• For any package identified, it would be good to have a sense of the kinds of datasets contained
