I would like to ask for advice from R experts about the benefits or dangers of using attr to return information with an object that is returned from a function. I have a feeling as though I have cheated by using attributes, and wonder if I've done something fishy. Maybe I mean to ask, where is the dividing line between attributes and instance variables? The separation is not clear in my mind

Hello. I spent an hour or three chasing down a desired effect that mootools implements, namely the simulation of onmouseleave and onmouseenter events. Why? Lets say you have a Menu. A ul element that contains many li elements. If you want to have a function (maybe an effect) fire when the mouse moves outside of the ul, you are out of luck. Observe the mouseout function like so:

Hi All, I think there may be some possible confusion about what allowsInf would be reporting (or maybe its just me :) ) if we did this. Consider a class "myclass", S3, for starters, with setMethod("allowsInf", "myclass", function(obj) FALSE) Then, what would myclassthing <- structure(1.5, class = "mything") myclassthing[1] <- Inf do. Assumely it

Roughly, our configuration is: Two IIS7 (Windows Server 2008 Web) servers which share configuration data and site files from a SMB share located on a ubuntu server.

I have a project for which I used a Wicket template as a starting point. The original example uses prototype.js. I''m using an SVG image as a background and have included a javascript that causes the image to always fill the background, regardless of the client window dimensions.

That is, more plugins, widgets, locked-and-loaded

I''m trying to apply a css class to all LI elements that are children of an element with the ID "idSelector". This is what I did and it works. But I was wondering if there was an easier way without having to use an anonymous function? $$("#idSelector li").each(function() { arguments[0].addClassName("myClass") }); Thanks in advance.
