First let me apologize for my failure to read emails. There was a
long-standing bug in the methods package where arguments passed as
"..." to a method would be dropped by callNextMethod(). It turns out
that in all known cases this affects calls to initialize(), probably
because there are many initialize() methods, and new() calls
initialize with "...".
This case is a very typical one, and Martin's fix is the right one,
according to the (unchanged) documentation of callNextMethod().
It's in general impossible to detect these cases from static analysis,
since we do not know how the user is calling a method. But catching
them in initialize() should be easy, with some false positives. Just
look for callNextMethod().
Is it OK for me to checkout all of Bioconductor so that I can perform
that analysis, or will that stress the servers too much? I have a
package that embeds GNU Global to index and search
CRAN/Bioconductor-size repositories for these cases.
Hi Michael -- there is no problem checking out all
(https://hedgehog.fhcrc.org/bioconductor/trunk/madman/Rpacks presumably) of Bioc.
Thanks! Martin

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.
