Because the check process does not consider R-level warnings in examples 
or vignettes, only errors.  Only someone who understands the code will 
know if the warnings are pedagogical, innocuous or serious.  No one says 
that examples should not give warnings, and it may be helpful to 
illustrate when they might occur.

It is possible to submit it, and very likely that it would be acceptable. 
Distributing a package with warnings you do not understand is not a good 
idea, though.
