[Rd] R CMD check: is it error to setMethod for class not currently defined?

[Gordon Smyth]

Should R CMD check consider it an error to define a new method using 
setMethod for a class which is not currently defined? It seems to me that 
it would be best not to consider this an error.

What currently happens in that setMethod issues a warning, quite correctly. 
This warning produces an object 'last.warning'. Then R CMD check issues a 
WARNING that 'last.warning' is an undocumented code object.

Would it be a good idea to make R CMD check disregard the object 
'last.warning' when checking for undocumented code objects? If people 
agree, I could try to make a patch for the R CMD check code.
