[Rd] How to connect R to Mysql?

[Spencer Graves]

       I've recently been through that with some success.  I don't 
remember all the details, but I first looked at "help(pac=RMySQL)".   
This told me that the maintainer was Jeffrey Horner.  Google told me he 
was at Vanderbilt.  Eventually I found 
"http://biostat.mc.vanderbilt.edu/wiki/Main/RMySQL", which told me that 
I needed to build the package myself so it matches your version of 
MySQL, operating system, etc.  I did that.


       Does the MySQL database already exist?  I created a MySQL 
database and tables using MySQL server 5.1.50-win32.  (Which version of 
MySQL do you have?)


       help('RMySQL-package') includes "A typical usage".  That helped 
me get started, except that I needed to write to that database, not just 
query it.  For this, I think I got something like the following to work:


d <- dbReadTable(con, "WL")
dbWriteTable(con, "WL2", a.data.frame)  ## table from a data.frame
dbWriteTable(con, "test2", "~/data/test2.csv") ## table from a file


       Hope this helps.
       Spencer
