[Bioc-devel] Unreproducible build check warning

Yes it's a little bit surprising (and questionable) that
'R CMD check' requires you to define an alias that is inconsistent
- Your setMethod statement:
setMethod("[", signature(x="scoreList"), ...
- The output of showMethods:
Function: [ (package base)
- The behavior of dispatch and selectMethod():
selectMethod("[", "scoreList") # works as expected
But, as Val pointed out, 'R CMD check' is the boss, and the only way
to make the warning go away is by adding the alias that 'R CMD check'
wants to see. Note that this alias suggests that the [ generic has
only 2 arguments in its signature so is not even consistent with the
signature of the generic (the [,scoreList,ANY,ANY,ANY-method alias
Note that the primary purpose of an alias is to make your man page
accessible by the user, not to please 'R CMD check'. So since the
user looking for documentation about the "[" method for scoreList
objects is more likely to access your man page thru your original
[,scoreList-method alias, I would recommend you keep it. Just add
the [,scoreList,ANY-method alias to please 'R CMD check'.
