Originally an amusing fancy printing system, this package contains that, as well as some functionality for showing. As of version 2.0, the package contains some helpful utilities for accessing hardware ram information, ram usage of the current R process, as well as some other niceties.
If you do a lot of benchmarking, this is the package you've been waiting for. Maybe. I mean, I don't want to be too pushy about it.
