| sysptm_dbconn {sysptm.db} | R Documentation |
Some convenience functions for getting a connection object to (or collecting information about) the package annotation DB.
sysptm_dbconn() sysptm_dbfile() sysptm_dbschema(file="", show.indices=FALSE) sysptm_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. |
sysptm_dbconn returns a connection object to the package annotation DB.
IMPORTANT: Don't call dbDisconnect on the connection object
returned by sysptm_dbconn or you will break all the
AnnDbObj objects defined in this package!
sysptm_dbfile returns the path (character string) to the package
annotation DB (this is an SQLite file).
sysptm_dbschema prints the schema definition of the package annotation
DB.
sysptm_dbInfo prints other information about the package annotation
DB.
