RSQLite problems
Hi, I'm experimenting with using (R)SQLite to do data management. Here are

Database newbee problem...
Hi all,
This is a potentially very stupid question about MySQL <-> R
interaction, but I have not been able to solve it.
I'm just trying to connect R to my MySQL databse, and gets this:
> library(RMySQL)
Loading required package: methods
> m <- dbDriver("MySQL")
> con <- dbConnect(m,group="testdb")
