R CMD check really hates it when my .onLoad() function contains

Note that you can always fool 'R CMD check' by doing something like:
sillyname <- library
suppressMessages(sillyname("foo"))
Also isn't suppressPackageStartupMessages() more appropriate?
However, _and for non-public packages not going to CRAN_ I prefer doing this
over using explicit Depends or import statements in the NAMESPACE file as the
latter do not give me an ability to make the loading less verbose. With the
R universe of packages being as vast as at is, a simple (non-public) package
I have loads about five or six other packages explicitly, each of which loads
even more. The net result is totally intimidating _sixty lines full_ of
verbose noise that is meaningful to me as an R programmer, but not for the
colleagues expected to use the packages. It looks rather uninviting, frankly.
How do I use imports via NAMESPACE, and yet keep the noise level down to zero?
If you only need to import foo (i.e. and actually don't need to attach
it to the search path) then putting foo in Imports and using import
statements in NAMESPACE will keep the noise level down to zero.
So I guess your question is: how do we suppress package startup messages
for packages listed in Depends?
Cheers,
H.
Dirk
