GO_dbconn: Collect information about the package annotation DB
In VincentL5201/GO.db: A set of annotation maps describing the entire Gene Ontology

Description Usage Arguments Details Value See Also Examples

Some convenience functions for getting a connection object to (or collecting information about) the package annotation DB.

  GO_dbconn()
  GO_dbfile()
  GO_dbschema(file="", show.indices=FALSE)
  GO_dbInfo()

`file`	A connection, or a character string naming the file to print to (see the `file` argument of the `cat` function for the details).
`show.indices`	The CREATE INDEX statements are not shown by default. Use `show.indices=TRUE` to get them.

GO_dbconn returns a connection object to the package annotation DB. IMPORTANT: Don't call dbDisconnect on the connection object returned by GO_dbconn or you will break all the AnnDbObj objects defined in this package!

GO_dbfile returns the path (character string) to the package annotation DB (this is an SQLite file).

GO_dbschema prints the schema definition of the package annotation DB.

GO_dbInfo prints other information about the package annotation DB.

GO_dbconn: a DBIConnection object representing an open connection to the package annotation DB.

GO_dbfile: a character string with the path to the package annotation DB.

GO_dbschema: none (invisible NULL).

GO_dbInfo: none (invisible NULL).
