abstract: 'A set of tools that solves a common set of problems: you need to break
  a big problem down into manageable pieces, operate on each piece and then put all
  the pieces back together. For example, you might want to fit a model to each spatial
  location or time point in your study, summarise data by panels or collapse high-dimensional
  arrays to simpler summary statistics. The development of ''plyr'' has been generously
  supported by ''Becton Dickinson''.'
