OK.  This seems to be the issue.  Basically I guess I could just ignore 
the messages --- but I'd really rather not see them.

The news() says they are printed by "default".  How can I move away from 
the default?

I presume that I need to invoke the suppressPackageStartupMessages() 
function, but it is not at all clear to me just how I should do this.

Perhaps I should put a call to this function in a *.R file
(e.g. "First.R") in my R directory.

I've experimented with various ideas; none so far have worked.  The 
function suppressPackageStartupMessages() takes an argument "expr".  It 
is not clear what "expr" should be in this context.

Perhaps I am barking up the wrong tree.

Any advice?
