Hello,
The library verbose option does not stop numerous messages
of the form "Loading required package: XYZ". This is inconvenient
when a package is loaded repeatedly using Rscript.
Is there a way to turn off the "Loading required package"
messages?

I do not think this suppress the messages when you attempt to load a
non-existent package. For that you may need to look at the options()
setting for warn and warning.expression
One possible work-around is to make packages Suggested
instead of Required, but this introduces other issues.
Thanks,
