I'm having issues appending data to a list which is already in a list format. I have a program which will export results objects during a simulation loop. The data itself is stored as a list of matrices. My idea is to store those lists in a list, and then save this list of lists as an R object for later analysis, however I'm having some issues achieving this correctly. I'll show what I've done with small abstract example just using values instead of the matrix data from my simulation: Say I've run the simulation loop for 3 times. During the iterations, the results lists need to be collected

This test plugin, is supposed to work like this: When an element is clicked, it moves down. Simple as that. jQuery.fn.moveDown = function(howMuch){ $(this).css("border", "1px solid black"); $(this).click(function(){ $(this).css("position", "relative"); $(this).animate({top: '+='+howMuch}); }); } The problem is, when an element is clicked, it not only moves the clicked element but also ALL the other elements which the plugin was applied to. What is the solution for this? For plugin authoring try this way, much more solid: Edit: Here is working jsFiddle example. PLUGIN: (function($){ $.fn.extend

I'm using Scala and I want to extend a (singleton) object with a trait, which delivers a data structure and some methods, like this: trait Tray[T] { val tray = ListBuffer.empty[T] def add[T] (t: T) = tray += t def get[T]: List[T] = tray.toList } And then I'll would like to mix-in the trait into an object, like this: object Test with Tray[Int] But there are type mismatches in add and get : Test.add(1) // ... How can I'll get this to work? Or what is my mistake? Travis Brown The problem is that you're shadowing the trait's type parameter with the T on the add and get methods. See my answer here

Need help with following situation: Users can generate their own data structures which are stored as JAXB-ready XSD sources like below: <xs:schema version="1.0" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="Group" type="Group"/> <xs:element name="Parameter" type="Parameter"/> <xs:complexType name="Group"> <xs:sequence> <xs:element name="caption" type="xs:string" minOccurs="0"/> <xs:element name="parameters" type="Parameter" nillable="true" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> <xs:complexType name="Parameter"> <xs:sequence> <xs:element name=

I have a class which I need to use to extend different classes (up to hundreds) depending on criteria. Is there a way in PHP to extend a class by a dynamic class name? I assume it would require a method to specify extension with instantiation. Ideas? I don't think it's possible to dynamically extend a class (however if I'm wrong I'd love to see how it's done). Have you thought about using the Composite pattern ( http://en.wikipedia.org/wiki/Composite_pattern , http://devzone.zend.com/article/7 )? You could dynamically composite another class (even multiple classes - this is often used as a

The main reason why I want it is that I want to extend my initialize function. Something like this: // main.js window.onload = init(); function init(){ doSomething(); } // extend.js function extends init(){ doSomethingHereToo(); } So I want to extend a function like I extend a class in PHP. And I would like to extend it from other files too, so for example I have the original init function in main.js and the extended function in extended.js . With a wider view of what you're actually trying to do and the context in which you're doing it, I'm sure we could give you a better answer than the
