Connecting to database on statup
...meters present in my.cnf file} dbname="mydbName")
DOES create a connection when entered into my R console individually but NOT when I place them in a function, i.e.,
condb <- function() {
drv <- dbDriver("MySQL")
dbcon <- dbConnect(drv, dbname="mydbName")
dbGetInfo(db)
}
When the function is called, the dbGetInfo(dbcon) does return connection info but no connection object is present.
I would be ver grateful for any guidance on where I have gone wrong. Thank you.

RMySQL NA/NULL value storage error
Greetings all,
I am running R 2.5.1, RMySQL 0.6 , and DBI 0.2-3 on Windows XP
Like others, I am having trouble with NA/Null value conversions between R
and a MySQL database via DBI, but I could not find my exact problem in the
archives. Most of the time NA values in R get transferred correctly to the
database and back again, unless (apparently) if they are in the last column
of the table being

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")
Process R segmentation fault at Wed Oct 16 07:04:30
