Dear All, I haven't seen any further comments about the problem that John Marsland first noted and that I also have:
library(DBI) library(RMySQL)
Warning message: DLL attempted to change FPU control word from 8001f to 9001f
It's a bad idea to ignore warnings! This says that there's a problem with the DLL that RMySQL is loading. It is attempting to change the rounding behaviour, and R is fighting back. I don't know if that would cause the error below, but it's a possibility.
mgr <- dbDriver("MySQL")
con <- dbConnect(mgr, host="localhost", dbname="marketing")

... I've cc'd this to the RMySQL maintainer David James; David J, if you don't know what I'm talking about regarding rounding, I'd be happy to expand on it. Duncan Murdoch
