RJDBC cant find driver class in JDBC jar file
I would like to set up a Windows XP environment with R and MySQL. This set-up was recommended by a friend who uses this set up, but I have been unable to get RJDBC to work. I have installed all of the software today (June 2 2008), first deleting and then replacing old versions of software.

RJDBC and multiple classpaths
Corect me if this is not the right place to post this. I have a mdbdriver.jar (to access an MSAccess file) under Linux. I bought the license from http://www.csv-jdbc.com/ guys. The driver work fine when tested with DBVisualizer or another JDBC thing. The problem is that driver needs 3 other more jar files to work.

RJDBC vs RMySQL vs ???
I am running a simple SQL SELECT statement that involvs 50k + data points using R and the RJDBC interface. I am facing very slow response times in both the RGUI and the R console. When running this SQL statement directly in a SQL client I have processing times that are a lot lot faster (which means that the SQL statement itself is not the problem).

The proper SQL format is: SELECT * FROM this_table WHERE this_column IN (1,2,3,4,5) But, I think I may be getting something like: SELECT * FROM this_table WHERE this_column IN c(1,2,3,4,5) Which makes no sense in SQL. I think it may be just a matter of string massaging, but I'm not
