strip_splits

This is useful when you want to perform some operation to every column
in the data frame, except the variables that you have used to split it.
These variables will be automatically added back on to the result when
combining all results together.

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'.
