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?

There's no need for manual steps. To take advantage of MySQL's
extremely fast 'load data infile' you could dump the data in CSV
format, write a script for mysql
That was just an example -- it's not difficult to write an R function
to generate the mysql create table syntax for a data frame with 60 or
600 columns. (BTW, I would never type 67 columns.)
