Hi, I'm trying to understand R's object oriented abilities. I have read (in a very recent email to r-help) that R's methods package does not support private methods. However, I also looked at the source for the function "is": > is function (object, class2) { cl <- .class1(object) if (missing(class2)) return(extends(cl)) if (.identC(cl, class2)

Also, check the settings of R_HOME and/or R_LIBS.

Hi, When starting an embedded R I encounter the following issue under certain conditions: ``` Error: package or namespace load failed for ?utils? in if (.identC(class1, class2) || .identC(class2, "ANY")) TRUE else {: missing value where TRUE/FALSE needed ``` (more such errors for grDevices, graphics, and stats) And in the end: ``` Warning messages: 1: package ?utils? in

Look at section 6.1 of the R Installation and Admin manual. 6.1 Default packages The set of packages loaded on startup is by default > getOption("defaultPackages") [1] "datasets" "utils" "grDevices" "graphics" "stats" "methods" (plus, of course, *base*) and this can be changed by setting the option in startup

Hi all, I'm trying to install the OOP package (http://www.omegahat.org/OOP) but having difficulty in resolving the errors generated during compilation. Googling doesn't seem to be giving much help. Can anyone please help. Below is the transcript of what I get from my command prompt. (I'm running on rw_2.0.0 WIN XP SP2 platform). Thanks in advance ---transcript---- Microsoft

hello, if i load the RSQLite package in addition to the RPostgreSQL package, i get various errors when trying to use RPostgreSQL functions. here is an example transcript showing one such error: ========================================================== R version 2.15.0 (2012-03-30) [...] > packageVersion('RPostgreSQL') [1] 0.3.2 > packageVersion('RSQLite') [1] 0.11.1

Hi, I'm new to OOP in R so please forgive the naiveness of some of the questions. Here are a couple of them. It would be great if you can contrast to OOP in Java. 1. R's S4 appears to centered around a dispatch mechanism which in my understanding is just a way to implement polymorphism. Now, here's the snag, I thought polymorphism was an aspect of OOP not by itself the definition of

I have a few questions and thoughts regarding class versioning and serialized S4 class instances. How is the version argument to setClass is intended to work? It appears to want an externalptr, but that seems odd to me. setClass("FOO", representation(x="numeric"), version="1.2.3") Error in validObject(.Object) : invalid class

Hello,   Does anybody know if the OOP module (Chambers & Temple Lang) is going to replace the the S4 (and the S3) class system? http://www.omegahat.org/OOP/oop.pdf Cheers!! Albert-Jan ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ All right, but apart from the sanitation, the medicine, education, wine, public order, irrigation, roads, a fresh water system, and public

Hi all, I've been having a look to all OOP functionallity in R, basically I've been reading "Statistics and Computing" book by Chambers. My problem is that I'm thinking about refactoring many functions of the applications I work with (which is quite huge), in order to modularize its components. I believe that trying to use OOP functionality may help to reorganize and

Hello R users, I am trying to make a my first package and I get an error that I can understand. The package is build out of three files (one for functions, 1 for s4 classes and 1 for s4 methods). Once I source them I run package.skeleton( name="TDC" ) within a R session and I get Creating directories ... Creating DESCRIPTION ... Creating Read-and-delete-me ... Saving functions and

Hi, I read section 5, oop, of the R lang doc, and I am still not sure I understand how to build a class in R for oop. I thought that since I understand the oop syntex of Java and VB, I am wondering if the R programmig experts could help me out by comparing and contrasting the oop syntex in R with that of Java. For example, the basic class structure in Java is like this: public class Bicycle {

Hello everybody, please excuse my bad English. I am Alfredo Naime and I'm from to Venezuela. I want to make a lib with tools for simulation (queues, inventories, factory, etc.) using object-oriented programming (OOP). You have any manuals on the handling of data types, classes, inheritance, etc. in R with examples and how to make a R lib. Thank you, very much. Alfredo

Dear list, I'm aware that this post does not really comply with the posting guide with respect to "providing a minimal reproducible code example". But I do hope it's okay that I spared uninterested readers by putting that into the attachment ;-) The thing is that I'm not really familiar with "true" OOP as R is my first programming language. So I wanted to ask

Can anyone recommend good books, online tutorials, or any other learning materials for Javascript - specifically Object Oriented Programming using JS? I want the rest of my dev team to be able to help me code in JS, specifically using prototype and scriptaculous. I''ve been using JS for so long, and I kinda "grew up" on OOP programming but my whole team is Coldfusion

Hello, I am writing a package with a collection of several models. In order to allow users to play interactively with the models (in contrast to hacking lengthy scripts), I want to put all what is needed to run a particular model into a single list object for each model. Then there will be a collection of functions to run the model or to modify parameters, time steps, integration method ...,
