similar to: "Incompatible methods" for overloaded operator

Hi, from the man page ?methods, I expected to be able to build pairs (class,package) for a given S3 method, e.g., print, using attr(methods(print), 'info'). However all the methods, except the ones defined in base or S4 methods, get the 'from' value "registered S3method for print", instead of the actual package name (see below for the first rows). Is this normal

When a reference class method is accessed with .self$x, it has different behavior from .self[['x']]. The former copies the function to the object's environment (with some attributes attached), and the latter just return NULL (unless it has already been accessed once with .self$x). Is this how it's supposed to work? Here's an example that illustrates:

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

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 ...

What it looks like is happening is roughly like this: - `p` is an environment and `p$e` is also an environment. - There is a loop. In each iteration, it looks for one item in `p$e`, saves it in a variable `x`, then removes that item from `p$e`. Then it invokes `x()`. The loop runs

I'm getting an R CMD check warning with a package (call it package A) that defines an S3 method but not the generic. The generic is defined in another package (package B). Package A imports the S3 generic from B. And there's one additional detail: the generic overrides a function in the stats package. I've created a minimal test package which reproduces the problem:

[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've been seeing warnings when unloading packages. They can be seen with the shiny and sp packages, among others (this is on R 3.0.2). For example: > library(sp) > unloadNamespace('sp') Warning messages: 1: In FUN(X[[2L]], ...) : Created a package name, ‘2013-12-19 12:14:24’, when none found 2: In FUN(X[[2L]], ...) : Created a package name, ‘2013-12-19 12:14:24’, when none

Hello, I try to set up namespaces for packages. It is fine for several of them, except one whose compilation fails (under Windows XP & R 2.0.0): ---------- Making package svViews ------------ adding build stamp to DESCRIPTION installing NAMESPACE file and metadata Error in parse(file, n, text, prompt) : syntax error on line 21 Execution halted make[2]: *** [nmspace] Error 1 make[1]: ***

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

When running R CMD check on a package, we are encountering an error on R-devel (as of 72457) on Linux. Unfortunately, it is very hard to reproduce, and almost any change to the code makes the error go away. I believe that this is due to a bug in R-devel, which has been present since at least commit 72128 (on 2017-02-06). The test error occurs when R CMD check is run on Travis CI (on Ubuntu

Hi all, I'm currently working on the fitdistrplus package (that basically fit distributions). There is something I do not understand about the generic function summary. In the current version on CRAN, there is no NAMESPACE saying S3method(summary, fitdist) . However if we use summary on an object send by fitdist function it works fine... According to R-lang, we have " The most
