Re: [Rd] method using several (and different) arguments in turn

Dear Martin, I could not entirely follow your suggestion. I can see how you define two classes inheriting from TypeOfSample, and how these two classes have two associated methods (incidentally, I'm unfamiliar with the: function(type,x=numeric(),...)to do. J expression. What is type?

[Rd] how to define method for "+" function in a new class

Dear R developers, I have a new class, which I called "Molecule", and have tried to define = a "+" operation for 2 objects of this class. This is what I have written so far, although the method is not complete = (I'm trying to look at it at intermediate stages): setMethod( f=3D"+",
