similar to: R.oo modify an object inside another classes method

I thought I would post an example of using R.oo with inheritance and pass by reference for future searches. With PerMore I am inheriting Person. Then I am changing an object data memeber of an object of PerMore class using pass by reference ('mimiced' by R.oo) in an object of AgeMultiplier. I change a data member in the child class and the parent class for demonstration purposes. This is

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

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",

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 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 )

How can I define a static member of a class? not a static method, rather a static field that would be accessed by all instances of the class.

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) {

Has anyone figured out how to create a destructor in R.oo? How I'd like to use it: I have an object which opens a connection thru RODBC (held as a private member) It would be nice if the connection closes automatically (inside the destructor) when an object gets gc()'ed. Thanks in advance. Regards, Ken BTW, a >BIG< thanks to Henrik Bengtsson for creating the R.oo package! Lucky

When I run R CMD check R.oo on R v2.7.0 devel (2008-03-04 r44677) on WinXP I get the following error while testing examples: Error in match(x, table, nomatch = 0) : formal argument "nomatch" matched by multiple actual arguments Calls: setMethodS3 -> setMethodS3.default -> %in% -> match Execution halted How is that even possible with: > get("%in%") function (x,

Hi, I'm using natural cubic splines from splines::ns() in survival regression (regressing inter-arrival times of patients to a queue on queue size). The queue size fluctuates between 3600 and 3900. I would like to be able to run predict.survreg() for sizes <3600 and >3900 by assuming that the rate for <3600 is the same as for 3600 and that for >4000 it's the same as for

Folks- First, let me submit a disclaimer... I know 1.3.12 is unsupported. However, since icecast2 isn't officially released, I'm abit SOL anyways, so I'm currently trying to debug it and will release a patch when I'm done. (Which I'm doing since the code is GPL and I want to contribute... if no one cares, let me know and I'll stop updating the list with what i find)

Hi all, I am building R 2.12.0 patched this morning from source on Snow Leopard (10.6.4). In fact, three times now, with separate clean source and build directories each time, just to be sure that the issue is predictable. I would be happy to have somebody tell me that I am missing something fundamental here also... After running make check-all, I get the following error for 'nlme': *

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

I got the following warnings when I install R.oo. Are these warnings normal? Should I reinstall the package as mentioned in the warnings? How to reinstall? The sessionInfo() is at the end. > install.packages("R.oo", dependencies=T) Warning in install.packages("R.oo", dependencies = T) : argument 'lib' is missing: using '/utility/R' also installing the

There are different way to make R classes. I know R.oo and S4. I'm wondering which one is the current popular one. Which one is current recommended when make new R packages? Thank you!
