Dear All,Can somebody explain me how to correctly set a new class-specific method for generic functions (e.g. for "plot", "summary" and "print"). I simply programmed these functions with the class names and it works perfectly. E.g.: x<-2 y<-3 class(x)<-"newclass" class(y)<-"newclass" print.newclass<-function(x){ cat(x*10) } print(x) print(y) However, I need the new methods for a new package, and the "R CMD check" gives me warnings that my approach is not correct. I have to define "methods" and do not use full names as "print.newclass". I read the "Writing R Extensions" and it is not explained there (at least to such level that I could get it) and I didn't get anything understandable by googling. Maybe someone can help me?
You need to declare methods in the NAMESPACE file, and there is special markup for them in Rd files.
