Reshape2 is a reboot of the reshape package. It's been over five years since the first release of the package, and in that time I've learned a tremendous amount about R programming, and how to work with data in R. Reshape2 uses that knowledge to make a new package for reshaping data that is much more focussed and much much faster.

This version improves speed at the cost of functionality, so I have renamed it to `reshape2` to avoid causing problems for existing users.  Based on user feedback I may reintroduce some of these features.

What's new in `reshape2`:
