Hi R-devel, The following code: all.equal(baseenv(), baseenv()) gives the error when run in a clean R session with latest R-devel (r66650): kevin:~$ R --vanilla --slave -e "all.equal(baseenv(), baseenv())" Error in all.equal.envRefClass(target[[i]], current[[i]], check.attributes = check.attributes, : attempt to apply non-function Calls: all.equal ... all.equal.list -> all.equal -> all.equal.envRefClass Execution halted Although I don't know if it's helpful -- it appears that packages that include som...

Dear list, is there a shortcut-function to check whether a class is a Reference Class or not? There's something like this for S4 classes ('isS4(object)'), but I couldn't find anything regarding Ref Classes. Currently, I'm doing it this way, which is a bit clumsy: A <- setRefClass("A", fields=list(X="numeric")) a <- A$new() isRefClass <-

> setRefClass("Foo", fields = list()) Error in setRefClass("Foo", fields = list()) : A list argument for fields must have nonempty names for all the fields In my opinion, the above should not fail. There are no fields. Thanks, Michael [[alternative HTML version deleted]]

Dear list, I don't know what's the correct term for this in the OOP context, but is it possible to "clone"/copy an instance of a reference class (say 'a') so that I get an *autonomous* second instance 'b'? Autonomous in the sense that changes to 'a' do not affect 'b'. I know that this is somewhat against the pass-by-reference paradigm, but the

Javier, Creo que aquí aplica la ley de Linus que dice: "Dado un número suficientemente elevado de ojos, todos los errores se convierten en obvios". La persona que revisa y encuentra un error no necesariamente tiene que ser la misma que la que lo escribe. Una motivación muy importante al compartir un código es la de recibir los beneficios del control de calidad por parte de tus pares.
