I fell into the same "hey it's a vector so && has to be

I'm already pretty sure the wrong code starts with omittedSig <- sigNames %in% fnames[omitted] # .... ------------- *Still* I cannot understand why in my case (and probably Peter, as he also said he can't reproduce), the conformMethod() function is not even called when I run loadNamespace("oligo"). As conformMethod() is *only* called from setMethod(), I've started trace()ing setMethod() and indeed, it is *only* called one, and not with oligo methods/generics,... Henrik, do you per chance not install packages in the usual way, i.e., do you install them without saving all the pre-computed classes and methods tables etc, and that would be *why* these setMethod() etc are only called at this point in time ?
