This could be one of those cases where your system (which CPU, what
compilers?) is unusually inaccurate, but Linux systems do not usually
differ much in their accuracies on the same CPU.
I've checked several systems, as see maximum values of around 40.

If so, this is a known problem with Rmpi, which I reported to the

Your first example does not call print(), so it is not suprising that no

What you want to do is very easy in RODBC, for example, but can be done

The R posting guide asked you to ask the maintainer, but as this is a

It's a _package_ that you are looking for (there is something else called
a gpclib library, to do with GNU Pascal).
You haven't told us your OS or R version, so we don't know what file you
