Hey Cats, I''m having a problem. I''m working with an object that contains a bunch of arrays: var myObject = { "data": [ {"line": [1,"aoo","far"]}, {"line": [2,"boo","ear"]}, {"line": [3,"coo","dar"]}, {"line":

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

Hi all, I am very new to Ruby and I have a silly question: how do I get RoR to "recognize" that I just defined a class? To be more explicit, I have a controller and view, and then I want to create a class and get the controller to "see" it. So, I created a file called "myobject.rb" in the models/ directory and inside it defined "class myobject [...] end".

Dear R users! Several languages like C# or VB allow one to create properties; typically these are under 'get', 'set' tags. My question is this really, what are similar or comparable strategies in R, and what might be preferred? I have a couple of situations where I want a certain computation to belong to a class, but I do not really want to seperate it out to a stand-alone

Hello Everyone: As usual, thanks in advance for any help. I was hoping to get some more advice on this question: I'm trying to write a subsetting routine for an S3 object I've created -- lets call it myObject. myObject has a few attributes basically of type string and numerics. Its atomic value is just a vector of ints. I want to write my own subsetting routine to subset myObject in

Dear all, i generated several GLM objects, named myobject1 to myobject25. Now i'd like to update both of them. So i tried: for(ii in 1:25) { assign(paste("myobject.updated", ii, sep=""), update( myobject[ii] ,.~ + VAR2)) } Doesn't work I also tried to get all the names in a vector and update(names.myobject[ii],.~ + VAR2) Stiil doesn't work Any ideas

I need a single boolean which would be "globally" accessible to all instances of a class. Seems like the boolean should be in the class prototype, but I was troubled by the difficulty of setting the prototype boolean to true. Maybe I''m missing something? var MyObject = Class.create(); MyObject.prototype = { bSwitch: false, ... other methods and properties } var oMyOb1

Hi R-listers, I am trying to better undertand what we would call "functional paradigm" use of S/R to better map my programming activities in other languages. This little function is aimed to create an object (at the end end, it would have it's own class): -- myObject =function(){ list( a=1, foo=function(b) { cat("b:",b)

I''m trying to debug an a uncaught exception: Permission denied to get property Object.constructor error. I have some code like this: myObject.js ------------ function myObject (arg1, arg2, arg3) { //does some constructor related stuff } myObject.prototype.createSomething = function() { // do more boring stuff // return an Array; } manager.js ----------- var fakeHashMap = new

After retrieving a URL using an Ajax.Request... function onComplete (request, json) { // request.responseText holds the entire page Only the content contained in elementID = ''source'' is intended for display At this time, the following code works, but it disturbingly copies the entire page from the source URL into the target DIV $(''target'').innerHTML =

Dear all How can I obtain the name of the argument passed in a function? Here is a simplistic example of what I would like to obtain: myfunction= function(name) { print(paste("The parameter name was",unknownFunction(name)) } myfunction(myobject) [1] "The parameter name was myobject" Thanks Francisco

Dear listers, I am working since a while with the sp package and still wonder how the plot methods are managed with sp spatial objects. For instance, SpatialPolygonsDataFrame objects have obviously a plot method. However it cannot be found in the list provided by methods(plot) . Furthermore ?plot.SpatialPolygonsDataFrame, nor ?plot.SpatialPolygons, etc.. provide a help, though the lattice

I need to create a sort of transaction around some Active Record objects that perform many insert/updates. Example: class MyObject def transaction &block @my_var = value self.instance_eval block end end MyObject.new.transaction do Model.create Model.collection.create etc...... end I have a gem that add a method into AR::Base and I need to read

Hello, I'm trying to figure out how to create a data object, and then save it with a user-defined name that is input as a command line argument. I know how to create the object and assign it the new name, however, I can't figure out how to refer to the new name for a future operation such as save(). The code below creates an object and uses assign() to give it the user supplied name

Dear R experts, beginners and everyone else, I'm calculating "cumulative periodogram" using the command "cpgram" [1] from the MASS library. Here is a short example with the "lh" (hormone level) dataset: library(MASS) plot(lh,type="l",ylab="value",xlab="time", main="Hormone Levels (lh)") spectrum(lh,

This is slightly OT for which I apologise in advance, but I was wondering if anyone here has had any problems when making multiple ajax calls at the same time. I''m working on a large Intranet application which makes heavy use of ajax calls and the bugs are flying in from the testers that if they repeatedly click on a link that makes an ajax call then Internet Explorer can fall

You need a closure. onComplete: function (response) { NamedActionResponseHandler(theElement, response); } Is that what you mean?

Hello How can I test equality with two objects when they include some attribute that is BigDecimal? if I make something like this: it "should ...whatever" do obj = Factory.create(:my_object) ... MyObject.first.should == obj end. FAILS This fails because the object expected is different from the object gotten, and the only difference are the BigDecimal attributes, that are

I have a controller method as such: def delete @category = Category.find_by_name(params[:name]) @element_id = @category.name Category.delete_all(["name = ?", @category.name]) end (For the purpose of this exercise, category names are unique) I have the corresponding delete.rjs file: if @element_id page.remove :id => @element_id page.visual_effect :highlight,
