Let me add another scoping problem in R, this time with the snowfall package. If I define a function in my global environment, and I try to use that one later in an sfApply() inside another function, my first function isn't found any more : #Runnable code. Don't forget to stop the cluster with sfStop() require(snowfall) sfInit(parallel=...

I understand that one benefit of having static member functions is not having to initialize a class to use them. It seems to me that another advantage of them might be not having direct access to the class's not-static stuff. For example a common practice is if you know that a function will have arguments that are not to be changed, to...
I do this out of habit: function process( fn ){ // Some process that builds data return fn( data ); } It is not always necessary to return the callback, and I would like to know if there is any performance hit in doing that over simply calling the callback: function process( fn ){ // Some process that builds data fn( dat...
