i think these two code snippets exhibit a bug. they are identical but for the inclusion of an initial line in snippet [2] [1] setMethod("Math", signature(x = "numeric"), function(x) "Works") getGeneric("sqrt")(4) [2] getGeneric("sqrt")(4) setMethod("Math", signature(x = "numeric"), function(x) "Works")

Hi, namespaceImportFrom in base/R/namespace.R has the following: fdef <- methods:::getGeneric(genName, impenv) The definition of getGeneric is in methods/R/RMethodUtils.R starts with: getGeneric <- ## return the definition of the function named f as a generic. ## ## If there is no definition, throws an error or returns ## NULL according to the value of

I encountered a segfault when using lld to cross-compile for Windows (+MinGW) from Linux. The problem happens with objects built by gcc. The problem is that ObjFile::CreateRegular considers a PendingComdat to be valid (and later causes an illegal pointer dereference). The following patch fixes the crash: diff --git a/COFF/InputFiles.cpp b/COFF/InputFiles.cpp index 9e2345b0a..f47d612df 100644

Hello all, I'd like to report a problem related to S4 classes. Platform: Mac G4/400 PCI (PPC-architecture) Mac OS 10.4.8 R 2.4.1 for Mac OS X (CRAN binary, 2006-12-19) w/ R.app 1.18 Last December, Simon Urbanek confirmed that the issue is not platform related, and that it is most likely a bug. He suggested to post my report to "the appropriate mailing list" -- I choose r-devel.

Can you upload a reproducer? You can create it using the /linkrepro flag.

There is a version of the methods package committed today that does dispatch in C for these functions. This should considerably speed up programs that define methods for these functions (specifically, having methods should only marginally affect the existing computations for the same function on basic vectors and objects). This is the first of several steps needed. Not quite all primitives are

i often find myself having a list of similarly-classed S4 objects and needing a list containing a particular extracted slot from those objects. so i did the following: > setMethod("slot", signature(object = "list"), + function(object, name) + lapply(object, function(i) slot(i, name))) Creating a new generic function for 'slot' in '.GlobalEnv' [1]

Hi, I'm writing some functions to generate Rd files for a S4 package. I want to have 2 character vectors with the names of the S4 classes and the methods exported by a package. To get the info about methods I'm using "getGenerics(where="package:FLCore")" however I can not find a similar process to get the S4 classes. Are there functions to access this information ? Best and thanks EJ

I have classes A and B, where B contains A. In the implementation of the group generic for B I would like to use the corresponding group generic for A. Is there a way to do that? I would also appreciate any comments if what I'm trying to do seems like the wrong approach. Here's a stripped down example: setClass("A",

Hi, I have a BioC infra-structure package that works fine (I can build, check and load it successfully) on revision r53950. The very same package fails on r54591 with the error below: Error in loadNamespace(package, c(which.lib.loc, lib.loc), keep.source = keep.source) : cyclic name space dependency detected when loading ?oligoClasses?, already loading ?oligoClasses? I don't see anything

I've had repeated problems with promptClass missing methods, usually telling me a class has no methods when it does. In my current case, I've defined an S4 class "mspathCoefficients" with a print method setMethod("print", signature(x="mspathCoefficients"), function(x, ...) { # etc The file promptClass creates has no methods in it. >

Hi the list I am creating a package and I have a problem to define a S4 method for plot. I define a class 'A' and a class 'B'. I want to define a function plot for signature c(A,missing) and another method plot for signature c(A,B). My code is the following : In /package/R/ directory: --- main.R --- setGeneric("plot",function(x,y,...){standardGeneric("plot")})
