export from R to MySQL

Hi R user!

What is the fastest way to export a large matrix or vector to a MySQL
database? The use of data.frame() and dbWriteTable() makes the process
slow, so is there any <direct> alternative?

Probably dumping to a text file and then using mysqlimport will be fastest,
in terms of computation time, but you will have to create the table by hand
(using SQL CREATE TABLE), so it might take just as much user time.
