That's what makes R kind of hybrid: both procedural and declarative. Declaring objects and its predicates and have all fully and efficiently processed without programming every single step may be shocking for those who only know the 'procedural way'. Except for the experience with SQL with which we do not write 'SQL programs', most programmers (including amateur programmers) never had contact with the declarative programming paradigm. Many may have never heard of Prolog, for instance. Cheers. -- Alexandre -- Alexandre Santos Aguiar, MD, SCT gpg public key: mailto:gpg...@asaguiar.net
