'rocker' Database Interface R6 Class - S3 functions
R6 class interface for handling database connections using DBI package as backend. The class allows handling of connections to e.g. PostgreSQL, MariaDB and SQLite. Although rocker is a R6 class, functions can be also accesses in classical S3 way.
# New database handling object db <- rocker::newDB() # Setup SQLite database rocker::setupSQLite(db) # Open connection rocker::connect(db) # Write table rocker::writeTable(db, "mtcars", mtcars) # Get query output <- rocker::getQuery(db, "SELECT * FROM mtcars;") # Close connection rocker::disconnect(db) # Reset database handling object rocker::unloadDriver(db)
