Just a quick note (from an R-core member) to those of you
(many ?!) who have S4 methods in  your packages:

R-devel [2.8.0 unstable] as of a few hours ago (svn)
does now also apply some of (Luke Tierney's) codetools package
checks to S4 methods.  For some reason it did check all regular
function definitions in a package, but not the S4 methods until now.

Consequently, you will see a bit more warnings in the output of 'R
CMD check' for 'R := R-devel', i.e., for "Bioc (pre-) 2.3" 
within a day or two at the package check page, i.e., at
