ETLUtils

ETLUtils provides utility functions to execute standard ETL operations (using package ff) on large data. Currently the following functions might be useful to you if you have some large dataset in SQL and want to import it immediately in an ffdf object

  • read.dbi.ffdf (reading of SQL data through DBI)
  • read.odbc.ffdf (reading of SQL data through RODBC)
  • read.jdbc.ffdf (reading of SQL data through RJDBC)

An example can be found at http://www.bnosac.be/blog/19-get-your-large-sql-data-in-ff-swiftly

Other utilities

Other functions include matchmerge, recoder, naLOCFPlusone and renameColumns.
