So, if I'm understanding this correctly, for a simple, one libpath() 
situation like mine dep = NA will catch depends and imports, while dep = 
TRUE will catch those two plus anything under suggests. From prior 
discussion and suggested reading I take it I would use dep = FALSE to catch 
the first two if I had multiple locations in libpath() while dep = TRUE 
behaviour would stay the same.

In putting the above code snippet into the Rprofile file, does it need to 
be all on one line or can it spread over multiple lines as it appears above?

My thanks for your time and patient assistance in finding the answers. It 
is very much appreciated and useful.
