I get a warning about "1 warning message" using R CMD check on the
survival library.  It comes from the code snippet:

   if (library(cmprsk, logical.return=TRUE)) {
        # further test of competing risks from survfit
        .
        .
        }
This is a very useful additional test when I'm checking any changes to
the affected code, so I like having this in my test suite even though it
doesn't run automatically.
This argues for a change in library -- when the user sets logical.return
=T they don't need a warning message too.  I submit this to the R core
and their collective wisdom.

I admit that mine is an unusual case, and for now I'll turn if off with
options(warn=-1)

Probably, wrapping in suppressWarnings() is better.
