Thanks Kevin, this indeed clarifies a bit the S3 method registration universe.

I'm trying to overload an operator, and I'm running into a strange problem. It happens when I install and load the package, but not when I simply source() the code. I'm defining + for two classes. The R code looks like this: #' @export #' @method "+" a `+.a` <- function (x1, x2) { message("Running custom + function") } #' @export #' @method

Hi, I started this post on bioc-devel but this seems to be more general: https://stat.ethz.ch/pipermail/bioc-devel/2013-May/004311.html See reproducible example from Martin below. Thank you.

Hi list, I've got a class B that contains a slot obj of class A. I'd like to be able to call all the methods of class A directly on objects of class B as if I had called the method on slot obj. This without overloading all methods of class A to work on class B. I don't define B as an extension of A, because I want class B to also work with objects of classes that inherit from

Hi, I was trying to get a list of S3 method for a given generic, along with the package in which they are defined, and I came across what looks like an issue in the data.frame returned in attribute 'info'. The column 'from' mostly gets the value "registered S3method for ..." except for visible methods. Is this the expected behavior? See code and output below. Thank you.

R-exts.pdf discribes S3method a little bit. But I want to understand more on how it is called, implemented and when to use it. I don't find it in an R session. But I see S3method() in some NAMESPACE files. > S3method Error: object 'S3method' not found > ?S3method No documentation for 'S3method' in specified packages and libraries: you could try '??S3method' I

I am writing my first R package, and I have been getting the following series of errors when I run R CMD check: * checking S3 generic/method consistency ...

tl;dr: S3 lookup no longer works in custom non-namespace environments as of R 3.6.1. Is this a bug? I am implementing S3 dispatch for generic methods in environments that are not packages. I am trying to emulate the R package namespace mechanism by having a ?namespace? environment that defines generics and methods, but only exposes the generics themselves, not the methods. To make S3 lookup work

[Env: R 2.11.1, Win Xp, using Eclipse/StatET] In a package I'm working on, I want to create as.matrix() and as.array() methods for a particular kind of object (log odds ratios). These are returned in a loddsratio object as the $coefficients component, a vector, but really reflect an underlying (R-1)x(C-1)xstrata array, whose attributes are contained in other components. I define coef,

I am cleaning up the rms package to not export functions not to be called directly by users. rms uses generic functions defined in other packages. For example there is a latex method in the Hmisc package, and rms has a latex method for objects of class "anova.rms" so there are anova.rms and latex.anova.rms functions in rms. I use:

Hi In NEWS, it says R CMD check now tests that the package can be loaded, and that the package and namespace (if there is one) can each be loaded in startup code (before the standard packages are loaded). For package "onion", I think I have followed all of sections 1.6.1 - 1.6.6 of R-exts, and it passes R CMD check for R-2.3.1. However, using R version 2.4.0 Under

Good morning, we recently observed a problem with importing S3 generics from a foreign package (without namespace), defining a S3 method in a package _with_ namespace and the `cleanEx()' function which is automatically generated and executed before examples are run by R CMD check. To be more precise. Package `strucchange' defines a S3 generic sctest <- function(x, ...)

Dear List, This may be related to this email thread initiated by Ben Bolker last month: https://stat.ethz.ch/pipermail/r-devel/2011-July/061630.html In answering this Question on StackOverflow http://stackoverflow.com/q/7195628/429846 I noticed that `methods()` was not listing some S3 methods for `plot()` provided by the mgcv package. At the time I wanted to check the development version of R as

I have updated the rms package to extensively use NAMESPACE. I cannot get certain S3 methods to dispatch. For example I have in NAMESPACE S3method(anova, rms) S3method(latex, anova.rms) anova.rms produces an object of class "anova.rms" and there is a latex.anova.rms function in rms. But when I do latex(anova(fit)) I get an invocation of latex.default. I have tried using
