Subject: empty array
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
