similar to: S4 class redefinition

Hi, I am facing with a strange behaviour of isClass and extends when these are called in .onLoad in both R 2.12.1 and R 2.13.0. This is preventing my package from doing some object initializations at a proper place (i.e. in .onLoad). Suppose one defines two S4 classes in a package, and that one needs to check the inheritance between these two when loading the package (e.g. to validate slots

Hi, I am having trouble installing the Open H.323 Channel driver in Asterisk. I have installed PWLib and OpenH323 V.1.11.7 This is the output l get before it bails out. asterisk:/usr/src/asterisk/channels/h323# make g++ -g -c -o ast_h323.o -march=i686 -DPBYTE_ORDER=PLITTLE_ENDIAN -DNDEBUG -DDO_CRASH -DDEBUG_THREADS -pipe -Wall -fPIC -Wmissing-prototypes -Wmissing-declarations -DP_LINUX

setClass("B", representation=representation("B", extra="numeric)) setClass("B", representation=representation(extra="numeric"), contains="B") Are these the same? If not, how do they differ? What about setClass("B", representation=representation("B", extra="numeric"), contains="B") ? As far as I can

Hi the devel list. I am adapting the package.skeleton to S4 classes and methods I would have been very proud to post a new working function on this list. Unfortunately, I do not manage to solve all the problems. Mainly - sys.source does not compile a file with setClass - dumpMethod does not exists yet In the following code, thise two problems are notified by a line ################# Still

Hi all, I am trying to extend a FunctionType to include new parameters. In particular, I want to ensure that the main function has been declared with both argsc and argsv. However there seems to be no easy way to accomplish this: llvm::Function::getFunctionType() returns a a reference to a const object, while modifying only the argument list yields an error during verification since the

It seems that if an S4 class has no slots it can't be instantiated because it is assumed to be virtual. Is there a way around this other than adding a do-nothing slot? A singleton would be OK, though is not essential. Problem: EmptyFitResult <- setClass("EmptyFitResult", representation=representation()) # also tried it without the second argument. same result. > e <-

Using R 2.4, the following fails: setClass("testc", representation(a="ANY")) makeC <- function(myarg) new("testc", a=myarg) makeC() -> Error in initialize(value, ...) : argument "myarg" is missing, with no default On the other hand, this is OK: f <- function(a) g(b=a) g <- function(b) if(missing(b)) "missing" else "valid

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",

Initialization of this simple hierarchy A = setClass("A", representation(x="numeric")) setClass("B", contains=c("VIRTUAL", "A")) C = setClass("C", contains="B") fails (neat that setClass returns generators; I hadn't realized that before!) > C(A()) Error: evaluation nested too deeply: infinite recursion /

Hi, I recently ran into this problem. I couldn't find any mention of it in the setClass documentation. setClass("Foo", representation(file = "character")) setMethod("initialize", "Foo", function(.Object, file) { print(file) }) setClass("Bar", contains = "Foo") And the error: Error in print(file) : argument "file" is

Hi, It's nice to be able to define S4 classes with slots that correspond to standard attributes: setClass("A1", slots=c(names="character")) setClass("A2", slots=c(dim="integer")) setClass("A3", slots=c(dimnames="list")) By doing this, one gets a few methods for free: a1 <- new("A1", names=letters[1:3])

I'd like to have two packages with S4 classes with the same name but different implementation. To that end I create a package tmpA with setClass("A", representation=representation( x="numeric"), sealed=TRUE) setClass("B", representation=representation( x="numeric")) B <- function(...)

Hi, I'm trying to make a new S4 object with a slot for a "link-glm" object. R doesn't like me have a slot of class "link-glm" > class(make.link("probit")) [1] "link-glm" > setClass("a",representation(item="link-glm")) [1] "a" Warning message: undefined slot classes in definition of "a": item(class

Dear colleagues, there is a behaviour with S4 (virtual) classes that I find very hard to understand: Depending on the position of setAs(), the tree of inheritance changes. This is my baseline example that defines the classes "grandma", "mother", "daughter" and a virtual class "mr_x". For a new instance if "daughter", "mr_x" is betweeen

I've fixed this and will commit soon. Disregard my dim<-() example; that behaves as expected (the class needs a dim<-() method).

When I define an S4 class ("B" in the example below) that directly extends another ("A" in the example below) , which in turn directly extends another ("character" in the example below), I find that the slot does not have the class I specified in setClass(), it has the underlying class. Is this an intended feature? Briefly, the reason for using this type of
