ETLUtils: Utility Functions to Execute Standard Extract/Transform/Load Operations (using Package 'ff') on Large Data

Provides functions to facilitate the use of the 'ff' package in interaction with big data in 'SQL' databases (e.g. in 'Oracle', 'MySQL', 'PostgreSQL', 'Hive') by allowing easy importing directly into 'ffdf' objects using 'DBI', 'RODBC' and 'RJDBC'. Also contains some basic utility functions to do fast left outer join merging based on 'match', factorisation of data and a basic function for re-coding vectors.

Version: 1.3
Depends: ff (≥ 2.2-13)
Imports: bit (≥ 1.1-12)
Suggests: RSQLite, zoo, DBI, RODBC, RJDBC
