similar to: setClass() and packages

If someone is able, can you tell me if there is a better way to do this? More specifically, do I have to rewrite all of the data members stuff and extend stuff of parent class in the child class? See below. Thanks in advance! Example 1: setConstructorS3("ClassA", function(A,x) { if(missing(A))A=15; if(missing(x))x=NA; extend(Object(), "ClassA", .size = A, .x=x

Hi to all members, i have a question about class inheritance and methods using R.oo package: I have the following code and it doesn't work, guess i'm doing smth wrong and there is nothing in the help. library(R.oo) setConstructorS3("ClassA", function(A=15) { extend(Object(), "ClassA", .size = A ); }) setMethodS3("print", "ClassA",

Hi Eli, Let's say I have a file ClassA.h, that pairs with a file ClassA.cpp to product a library libClassA.a. ClassA.h contains the single declaration. class A {...}; I want to transform it to: #include "ClassB.h" class A : public class B {...}; ClassB.h is the header file for a library libClassB.a built from ClassB.cpp and ClassB.h. I can clearly link libClassB with libClassA.

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 have implemented class specific behaviour of "[[<-.myclass"<-function(). How it is posible to call the "[[.default" on an object of myclass? Eryk Dipl. bio-chem.

I'm writing a code transformation that involves adding an include to existing code, adding a base class to and existing class and then linking with a previously compiled library. The main problem for me seems to be how can I add the include? Can I compile the include alone to byte code and pre-pend it? Should I compile the library, which includes the include and parse out the include and

Hi, have got anybody experience or a starting point for me, how i can program a function which calculate me a probability transition matrix with a data.frame and two states. I have some independend variable and a class variable for two states - in example one from Jan2003 and the same variables from June2003. Now i would like to calculate the probability that PERSON X change from classA to

Hi, I''m running Puppet 0.23.0 on my servers, and i got something like this: In a classa.pp file (included in site.pp): class A { file { "test1": ... } } In a classb.pp file (included in site.pp): class B { file { "test2": ... } if defined(File["test1"]) { ... do things ... } if

Hello everyone. R-2.12.0, suse linux 11.3. I am debugging a package that uses S4 methods and R CMD check gives the following warning: > Warning in methods::findMethods(g, env) : > non-generic function 'mdm' given to findMethods() > See the information on DESCRIPTION files in the chapter 'Creating R > packages' of the 'Writing R Extensions' manual. I

Hi R-community, I'm very busy with a software project which I would like to development completely with R.oo. Many of the object oriented aspects that I already know from Java development seems to be in place with this library. But...there is something that I'm really missing... *the super method call* Just a little example that shall demonstrate what I mean: Image we have the following

I see, Adding includes is trivial even w/o llvm, but the real problem here is manipulation of classes, if I understand you correctly adding an inheritee wouldn't be possible.

Dear List, I'm struggling with the signature writing cbind/rbind functions for a S4 class. First of all, I'm very happy that it is now possible to dispatch on ... I follow the example for "paste" in ?dotMethods, which works as far as this: ### start example setClass ("cbtest", representation = representation (data = "data.frame"),

Hello. This question concerns the Methods package. I have created a new class and am trying to set a method for it for S4 group generic "Summary". I have run into some signature problems. An example: > setClass("track", representation(x="numeric", y="character")) [1] "track" > setGeneric("max", group="Summary")

Dear list, It seems that S4 methods defined for an S3 'base' generic are not used in 'base' functions. This can be problematic when 'base' functions start with something like 'as.matrix'. ### START R code setClass("classA", contains = "matrix", representation(realData = "numeric")) setMethod("as.matrix",

Hi all, I came across an issue in using the Matrix package which made it that I could only subset Matrices using the numeric class, but could not using integers. Steps to reproduce the problem: library(Matrix) # this class has *nothing* to do with Matrix setClass("MyClass", representation(myvalue = "numeric"), prototype(myvalue = NA_real_)) # this class also has

Dear list, It seems that a package (pkgB) using another package (pkgA) with S4 generics formed by taking existing functions (for example 'plot') must not import the existing functions ('plot') in its namespace to avoid the warning "replacing previous import: plot". Suppose we use the simple 'import' directive in the name space of pkgB. pkgA and pkgB files would

Dear List, consider the following scenario: setClass(Class = "A", representation = representation(B = "B", C = "C")) setClass(Class = "B", representation = representation(C = "C")) setClass(Class = "C", representation = representation(something = "character")) Obviously, the collation for sourcing these defs needs to be: C,

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
