Databases: BerkeleyDB Database Operations and Methods
In RBerkeley: Oracle 'Berkeley DB' Interface for R

Description Details Value Author(s) References

Low-level calls to the BerkeleyDB API. These functions simply wrap most of the DB functionality and expose it at the R level.

Documentation on usage, valid arguments, and flags from the official Oracle C API should be all that is required to correctly use this API.
