Hi Michael,
Thanks for looking into this.
Can you or someone with push permission to S4Vectors implement the
workaround that you mentioned?
Happy to create a pull request on Github if that helps.
We’re trying to solve this to fix the clusterExperiment package build
on
Bioc-devel.
Thanks,
Davide

Yea it's basically

library(RNeXML)
is(1:5, "Annotated")
# Found more than one class "Annotated" in cache; using the first,

But can be worked around:
is(1:5, getClass("Annotated", where=getNamespace("S4Vectors"))
# [1] FALSE
Of course, using class objects instead of class names in every call to
is() is not very palatable, but that's how it's done in all other
languages, as far as I know.
There is an inconsistency between new() and is() when resolving the
class name. new() looks into the calling package's namespace, while
is() looks at the package for the class of the 'object'. The new()
approach seems sensible for that function, since packages should be
abstracting the construction of their objects with constructors. The
is() approach is broken though, because it's easy to imagine cases
like where some foreign object is passed to a function, and the
function checks the type with is().
I can change is() to use the calling package as the fallback, so
DataFrame(1:5) no longer produces a message. But calling it from
another package, or global env, will still break, just like new(). How
does that sound?
On the other hand, maybe we should be more careful with calls to is()
and use class objects. That's a good workaround in this case, anyway,
since I probably can't get the change into R before release.

only now it
is not the SummarizedExperiment class but the SingleCellExperiment
class that has the problem. [And I was incorrect, the problem does
occur in development version 2018-03-22 r74446].
So this is actually a problem with the SingleCellExperiment package —
sorry for the incorrect subject line.
All of the best,

Hello,
Our package clusterExperiment has suddenly started producing errors
in the bioconductor devel branch because our unit tests are
failing, even though we haven’t pushed any changes and they passed
previously. We first noticed this on April 5th.
I believe the source of these errors likely do to calls to
SummarizedExperiment() creating the following messages due to
conflicts in ‘RNeXML’ and ’S4Vectors’ both defining class
‘Annotated':
Found more than one class "Annotated" in cache; using the first,
from namespace 'S4Vectors'
Also defined by ‘RNeXML’
This is killing a vast number of our tests where we repeatedly use
‘expect_silent’ calls in our unit tests and SummarizedExperiment
calls underlie everything.
We had this message issue two years ago

KmPXPitPvrUgI&s=PsCvulwKcgNnhI8OtnUfHYf8C9LuPyz9sGQmzKhL_rc&e=>),
when it
appeared to be a problem with two definitions of the ‘Annotated’
class in two packages that are both dependencies of packages we
call. At that time, Michael Lawrence posted that he would fix the
problem, and it was then fixed in later versions of bioconductor/R.
But it appears to be back. I am unfortunately unable to get the
RNeXML package to compile from source on my computer with the
current Mac OS X development binary which I just downloaded (2018-
04-05 r74542), so I haven’t been able to completely redo the code
that we presented in that earlier github issue to confirm it is the
exact same problem. I am having to rely on the error reports/logs
from both Bioconductor and TravisCI (e.g. 2018-04-07 r74551), where
this message shows up everywhere and didn’t before. Thus I’m
guessing that since they are the same messages from before that the
source is again the call to SummarizedExperiment.
I would note that in development version 2018-03-22 r74446, where I
was able to install all of the packages, I was not getting these
messages.
Thanks,
Elizabeth Purdom
