hdd: Easy Manipulation of Out of Memory Data Sets
Hard drive data: Class of data allowing the easy importation/manipulation of out of memory data sets. The data sets are located on disk but look like in-memory, the syntax for manipulation is similar to 'data.table'. Operations are performed "chunk-wise" behind the scene. See <https://lrberge.github.io/hdd/> for more information.
