Dear all, I try to submit a library to CRAN but can't overcome the last R CMD CHECK. Can someone enlighten me how to put the \usage{} section for an S3-Method extractor defined as > args(get("[.refdata")) function (x, i = NULL, j = NULL, drop = FALSE, ref = FALSE) NULL I read the "Writing R Extensions" manual and know about \methods{generic}{class}, however I

...ss in a "constructor function" I can do something like this (correct?): myConstructor <- function() { return(new("TestClass")) } pippo <- myConstructor() > pippo An object of class "TestClass" Slot "lmOutput": <S4 Type Object> attr(,".S3Class") [1] "nls.lm" Slot "anumeric": numeric(0) And the object "pippo" seems correctly initialized. If I use this code instead I got an error: myConstructor2 <- function() { pippo <- new("TestClass", anumeric=1000) return(pippo) } > pippo...

...initialize" method should take care of? Another singularity that is maybe at the root of all of this is that the "formula" S4 class is virtual: showClass("formula") # Virtual Class "formula" [package "methods"] # # Slots: # # Name: .S3Class # Class: character # # Extends: "oldClass" so a bare call to new("formula") fails: new("formula") # Error in new("formula") : # trying to generate an object from a virtual class ("formula") Shouldn't new("formula&quot...

...ith a bug fix r46136 July 28). So if you can live with the limitations of the first point and would like to experiment with extending an S3 class, you're invited to try. Note that the S3 classes _must_ be registered via setOldClass() for extensions to work. See ?Classes, ?setOldClass and ?S3Class for details. John

I'm trying to write a generic function that calls different methods depending on the structure of the argument, but not the exact type of its contents. For example, the function 'nan2last' below works for a numeric vector but not for a vector of Date objects. Is there any way to make it work on any vector? setGeneric("nan2last", function(x) {
