Hi the list Is it possible to create an empty matrix ? I do not mean an matrix with a single value that is NA (which is not empty) but a real empty one, with length=0. I do not understand why we have length(numeric()), length(factor()) and length(character()) to zero, and length(array()) to one... Any rason for that ? Thanks Christophe
