R crashes with the following code. Lots of us would really would like to 
use R with MYSQL. 

So please help. As mentioned in another note, where might I find a 5.0 
libmySQL.dll?

PROBLEM A: the dbSendQuery (see below) SQL crashes R. Wants to send an 
error report to Microsoft. (MAJOR)
PROBLEM B: the initial library load points to an ancient mysql version. 
(minor)

Warning message:
In inDL(x, as.logical(local), as.logical(now), ...) :

   RMySQL was compiled with MySQL 5.0.67 but loading MySQL 5.1.31 instead!
   This may cause problems with your database connections.

   Please install MySQL 5.0.67.

   If you have already done so, you may need to set your environment
   variable MYSQL_HOME to the proper install directory.
 > mycon <- dbConnect(MySQL(), user='root', dbname="mysql", 
password='f5^b678&')
 > rs <- dbSendQuery(mycon,
+      "SELECT *
+      FROM precinct
+      WHERE `Precinct-Ballot Style` LIKE '1120%';"
+      )

Thanks,
