Stack: Stylized concatenation of data.frames or ffdfs
Version 2.0-1

Stacks rectangular datasets on top of each other, possibly performing several type coercions along the way. For large datasets, depends on the ff package. Provides an aggressive version of ffbase::compact for data that may appear be real-typed but is in fact int/short/byte. For many purposes plyr::rbind.fill may be more appropriate, but for some kinds of survey data, the rules here work better.
