similar to: R.oo data members / inheritance

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 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

Hello (Heinrich), I did not know I could do this. It doesn't seem to be documented anywhere. Thought this would be helpful to the fraction of the community using package R.oo. Note the call of a setMethodS3 method, xOne, in the setConstructorS3. This is extremely useful if xOne (in this case) is a very complex method (that you always want to be called every time you create a new object). If I

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.

Hello, I'd like to 'do work' on data members upon construction (i.e. without implementing it in a get method). Is this the best way to create data member 'z' upon construction? I'm thinking if .z=paste(x,y) below gets more complex I'll run into issues. setConstructorS3("MyClass", function(x=NA,y=NA,...) { this <- extend(Object(), "MyClass",

Where should the setClass() ('methods' package) calls be placed in a package? I try to follow a one-class-one-file principe, but since setClass("ClassA", "ClassB") has to come a after setClass("ClassB", [snip]) it is not possible to fully follow this rule. So the best I can do now is to put all setClass() calls in a file named "000.R" (I know this

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

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

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.

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 would like to use R.oo and tcltk to implement a Turtle World. I have encountered many problems because: 1) I am not sure how to implement static fields with R.oo 2) I am not sure how to implement a constructor that would call a function only for the first instance of a class (i.e., to initialize value of static fields only once) 3) I am not sure how to remove/delete cleanly existing

Dear R.oo package users, while testing some functionality of the R.oo, I found that during the first construction of a object from a class, the constructor is twice called, but only one object is finalized. In all subsequent creation processes, the constructor is (expectedly) called once. Here some example code: library(R.oo) setConstructorS3("Test_class",function(val) {

Can someone show me how to modify one (R.oo) class's object inside another (R.oo) class's method? Is that possible with the R.oo package? A quick example or reference to an example would be outstanding... Thanks, Ben [[alternative HTML version deleted]]

Hi Henrik, I'm sorry to be bothering you, but there is something that I have been stuck with for a while now. I am trying to create a class like : setConstructorS3("MyPTCM",function(tokenslist=0) { extend(Object(), "MyPTCM", .gamma = 0.0, .rho = 0.0, .phi = 0.0, .tokenslist = tokenslist, .uniquetokens = unique(tokenslist),

Hello, How do I inherit two classes using the R.oo package. Below is kind of a silly example, but I am trying to create class PerDog from classes Dog and Person. Error at bottom. I've tried a few other ways of using extend(), but nothing seems to get me what I want. Example: setConstructorS3("Person", function(age=NA) { this = extend(Object(), "Person", .age=age )

Hello, I noticed (due to a recent post by Martin Honnen to clp) that Element.Class uses wrong regexps for its operations. E.g., Element.Class.has() will find "classA" in "classA-foobar" I also changed the interface of .has() to the more general one used in .has_any() --- util.js.old 2005-08-21 19:18:40.000000000 +0200 +++ util.js 2005-08-21 19:31:42.000000000 +0200 @@

I have two more or less parallel dataframes that are giving me different results on one subset of variables. I know that I assembled the 2 dataframes slightly differently but I don't see why I am getting this result because one set of variables are labelled and the other is not. Variable names are the same, etc. as far as I can acertain. The only diffference seems to be that bdata variables
