I created some S4 objects that are essentially data frame objects. The S4 object definitions were necessary to verify data integrity and force a standardized data format. I am, however, finding myself redefining all the typical generic functions so that I can still manipulate my S4 objects as if they were data frames ... I have used setMethod to set methods for "subset", "head", and "tail". I would like to use setMethod or setGeneric to enable me to use object$slotname to access obj...@slotname for my S4 objects. Any advice is appreciated. Thanks. --Markus
