r-cran-plyr - 1.8.9-1 main

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).
