You are right.

I thought Michael Lawrence (member of R Core since last summer!)
was also reading Bioc-devel, so wonder why he has not yet
replied --> CC'ing him

The changes to R-devel also did break the Matrix package in
exactly the same way.  You said

Here is the |initialize|method for |parameterFilter| which causes the
various errors from flow package vignettes.

|setMethod("initialize",
            signature=signature(.Object="parameterFilter"),
            definition=function(.Object, parameters,...)
            {
              if  (!missing(parameters))
                parameters(.Object) <- parameters
              callNextMethod()
            })
|

and I also had  a  _no argument_ call
       callNextMethod()
inside an  initialize method.

I'm pretty sure that if you change (the same as I)

            callNextMethod()
to
            callNextMethod(.Object, ...)

you'll have a version of the code that works both in current R 3.1.2
(and older versions)  *and* in the R-devel version.


I also pinged Michael??

What's a precise statement of the problem -- no-argument callNextMethod() inside initialize? Any suggestions on ways to discover these without relying on package break during build / check / install?

Martin Morgan

Michael L and I were not sure how many other packages or R code this
would influence and he was expecting very very few.
