Dear all, Assume that I have an S4 class "MyClass" with a slot "myname", which is initialized to: myname="" in method("initialize"): myclass <- new("MyClass", myname="") Assume that class "MyClass" has a method "mymethod": "mymethod.MyClass" <- function(object, myname=character(0), ...) {

Hi, The following question might come from my (deep) misunderstanding of the concepts in the package 'methods'. I have a class 'A', and a class 'B' inheriting 'A' (so defined with 'setClass' and the parameter 'contains="A"'. The class A has a method 'mymethod'. A call to 'showMethods("mymethod")' return the

Apologies for asking something that is probably super obvious, i just started with S4 classes and i guess i am not finding documentation that layout the grammar rules and give enough examples. Some questions i am having are these 1. I understand that main method of writing a member function is to write a generic function and setMethod for this particular object. This, however, presumes that there

Hi, Strange things happen. Here is a simple example: > setClass("A", contains="integer") > setMethod("as.matrix", "A", function(x, ...) t(callNextMethod())) Creating a generic function for ?as.matrix? from package ?base? in the global environment [1] "as.matrix" > a <- new("A", 1:3) > as.matrix(a)

I've got some calls like: musttail call void bitcast (i32 (i32, i8*, %Type*)* @MyMethod to void (i32, i8*)*)(i32 %0, i8* %1) ret void Into something like: %8 = tail call i32 @MyMethod(i32 %0, i8* %1, %Type* null) ret void I realize I'm losing a parameter there, but this is an interface jump trick I use and relies on the end code being a 'jmp' (x86). I realize i can probably

Hi all, I'm trying to implement the matrix multiplication operator, which is S4 generic, for an old-style S3 class. The following works as expected: x <- 1:10 class(x) <- "myClass" setOldClass("myClass") setGeneric("myMethod", function(x, y) standardGeneric("myMethod")) setMethod("myMethod", c("myClass", "myClass"),

I'm trying to make a function to turn a regular function into an S3 generic one. I want myMethod to be: function(x,...) UseMethod("myMethod") But I keep getting: function(x,...) UseMethod(func) Here's the function: toGeneric<-function(func) { env<-environment(get(func)) # default method of new generic = the original function

Hello Rubyists, I ran into a problem with sorting a table (rendered in a partial) using the sort_link_helper methods after I have submitted data and re-rendered the table through an AJAX request. The setup is a follows: The table is a shared partial of Controller1 and Controller2 accessible via "shared/table". The AJAX''ed sorting using the sort helper works all fine on

Hi, I have method I want to call ... it can receive * number of parameters. I also have 3 parms that I want to pass often, so I have defined them in a separate function: def my_params { :parm1 => 1, :parm2 => 2, :parm3 => 3 } end And I want to call my method like this: mymethod :parm4 => 4, my_params Now - this doesn''t work - as my_params is a hash of params, which

The %*% function is a primitive. As it says in the documentation under ?Methods_Details Methods may be defined for most primitives, and corresponding metadata objects will be created to store them. Calls to the primitive still go directly to the C code, which will sometimes check for applicable methods. The definition of ?sometimes? is that methods must have been detected

How can I "get" the rails logger from a plain class, that is a class that does not inherit from a rails class? I have tried using RAILS_DEFAULT_LOGGER (see below) but it''s nil class MyClass logger = RAILS_DEFAULT_LOGGER def myMethod logger.debug("stuff...") end end -- Posted via http://www.ruby-forum.com/.

Greetings, I had a question about the $super argument that I wasn''t able to find in documentation, searching etc. What exactly is the $super argument. Is it a reference to the super class''s prototype function? Or is it an instantiated object of the super class that is passed to the subclass''s method? I am completely confuzzled on this one, my typical

A few days ago, someone asked me why I am using wxpp instead of SWIG. The question prompted me to revisit and re-evaluate SWIG, and I now believe it would be best to convert wxRuby to SWIG. SWIG has greatly improved its C++ support since the last time I looked at it, and I think its Ruby support has improved quite a bit as well. Also, now that I have written wxpp, I understand the nature of

I wish to extend ActionMailer::Base by method chaining a class instance variable: module ActionMailer class Base class << self def method_name ... What is the magic incantation to accomplish this? I cannot get this to work with action mailer: module MyMethods def self.include(base) base.alias_method_chain :method_name, :my_method def method_name_with_my_method ... stuff method_name_without_my_method end ... end class ActionMailer::Base include MyMethods end require ''my_methods'' -- Posted via http://www.ruby-f...

Hi, this is perhaps not so much an issue, but as you are currently working on the Rd parser anyway... When you want to document specific S4 methods for an S4 generic by \S4method{} within a \usage{} environment, and the second (signature_list) argument is "long", be it because you use multiple dispatch, be it because you use long class-names, (or both), one would probably like to be

Hi all, I'm seeking feedback (good, bad or indifferent) in regards to developing (further) a new class system for R, that uses encapsulated class definitions (i.e. the method definitions are literally inside the body of the class definition). A working (however very rough and poorly tested) system is available in my R package "oosp" with documentation in the vignette

RSpeckers: I''m trying to install this into a Merb-generated RSpec rig: http://code.jeremyevans.net/doc/fixture_dependencies/ It requires inserting their test case into RSpec. This is the documented way to do it: describe ''Post'' do inherit FixtureDependencies::SequelTestCase And that leads to the syntax error in the subject line. (No stack trace is available

Dear all, I am experiencing some problems with S4 method overloading. I have defined a generic for graphics:plot, using setGeneric("plot", useAsDefault = plot) and with importFrom('graphics', 'plot') and exportMethods('plot') in the NAMESPACE file of pkg A. I then proceed to define a method for signature c('myS4class', 'missing'). This works

Hi all, Using R a as a real-time application called by Php for a website, I would like to run one R process only, which would manage user connections. For the time each user who asks for an analysis causes a new R process to start, which is not suitable in prevision of many users. R needs about 30 seconds to run the script which makes the analysis. The problem is that this waiting time is n
