Subject: [Rd] R-devel new warning: no longer be an S4 object
Message-ID: <CAOO9MKVd0EYf8knZuZhbhAGy-J80b2qovhDAmR08Qe3077GGMg@mail.gmail.com>

Hi R-devs,
R 4.0.5 gives no warning. Is it expected? Searching the news for "I("
doesn't give any info. Thanks

z = I(getClass("MethodDefinition"))
Warning message:
In `class<-`(x, unique.default(c("AsIs", oldClass(x)))) :
  Setting class(x) to multiple strings ("AsIs", "classRepresentation",
...); result will no longer be an S4 object
