The data.table package provides a high-performance interface for querying and manipulating data tables (a close cousin of data frames). In the video below (recorded at the H2OWorld conference), creator Matt Dowle gives a tour of the package and provides several examples of its use.
If you'd like to see the details on the example Matt presents at the beginning of the talk, you can find the post how the City of Chicago uses data.table for food safety, here.
