R devel - Oct 2010 - library verbose option doesn't stop "Loading required package XYZ"

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?

One possible work-around is to make packages Suggested
instead of Required, but this introduces other issues.

Thanks,
Dominick

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
