[R] Error with RMySQL

[Ashim Kapoor]

Dear Jim,

I restarted the mariadb.service but I am STILL not able to access the server.

I can access one database from one user but not from another user. The
credentials seem to be OK to me.

If I can figure this out I will post it here.

Many thanks,
Ashim
