Tools for splitting, applying, and combining data
plyr is 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 pieces 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 BD Becton Dickinson.
