Hello! How to set function for the whole R-class to be executed when the object is no more referenced from R and garbage collection takes place? I need the function to be applied for the whole class (let it be "someRClass") like this someRClass.on.finalize<-function(...){...}. I have found reg.finalizer function in the manuals, but it apply for the class instance, the thing that I do not like. What is the solution?
